ams OSRAM VCSELs in Melexis' in-cabin monitoring solution

ams OSRAM VCSEL illuminator brings benefits of integrated eye safety to Melexis automotive in-cabin monitoring solution

Premstaetten, Austria (11 May, 2022) – ams OSRAM (SIX: AMS), a global leader in optical solutions, announces that it is supplying a high-performance infrared laser flood illuminator for the latest automotive indirect Time-of-Flight (iToF) demonstrator from Melexis.

The ams OSRAM vertical-cavity surface-emitting laser (VCSEL) flood illuminator from the TARA2000-AUT family has been chosen for the new, improved version of the EVK75027 iToF sensing kit because it features an integrated eye safety interlock. This provides for a more compact, more reliable and faster system implementation than other VCSEL flood illuminators that require an external photodiode and processing circuitry.

The Melexis evaluation kit demonstrates the combined capabilities of the new ams OSRAM 940nm VCSEL flood illuminator in combination with an interface board and a processor board and the MLX75027 iToF sensor. The evaluation kit provides a complete hardware implementation of iToF depth sensing on which automotive OEMs can run software for cabin monitoring functions such as occupant detection and gesture sensing.

More reliable operation, faster detection of eye safety risks

The new ams OSRAM VCSEL with integrated eye safety interlock is implemented directly on the micro-lens array of the VCSEL module, and detects any cracks or apertures that can cause an eye safety risk. Earlier automotive implementations of iToF sensing have used VCSEL illuminators that require an external photodiode, a fault-prone, indirect method of providing the eye safety interlock function.

The read-out circuit requires no additional components other than an AND gate or a MOSFET. This produces almost instant (<1µs) reactions to fault conditions. A lower component count also reduces the bill-of-materials cost compared to photodiode-based systems. By eliminating the use of an external photodiode, the eye safety interlock eliminates the false signals created by objects such as a passenger’s hand obscuring the camera module.

“Automotive OEMs are continually looking for ways to simplify system designs and reduce component count. By integrating an eye safety interlock into the VCSEL illuminator module, ams OSRAM has found a new way to bring value to automotive customers. Not only will it reduce component count, but also increase reliability while offering the very highest levels of optical performance,” said Firat Sarialtun, Global Segment Manager for In-Cabin Sensing at ams OSRAM.

“With the EVK75027, Melexis has gone beyond the provision of a stand-alone iToF sensor to offer automotive customers a high-performance platform for 3D in-cabin sensing. We are pleased to be able to improve the value of the EVK75027 by now offering the option of a more integrated VCSEL flood illuminator on the kit’s illuminator board,” said Gualtiero Bagnuoli, Marketing manager Optical Sensors.

The EVK75027 evaluation kit with ams OSRAM illumination board can be ordered from authorized distributors of Melexis products (https://www.melexis.com/en/product/EVK75027/Evaluation-Kit-VGA-ToF-Sensor).

There is also a white paper on the new illumination board for the EVK75027, describing the benefits of implementing an iToF system with a VCSEL flood illuminator that includes an eye safety interlock.

"End-to-end" design of computational cameras

A team from MIT Media Lab has posted a new arXiv preprint titled "Physics vs. Learned Priors: Rethinking Camera and Algorithm Design for Task-Specific Imaging".

Abstract: Cameras were originally designed using physics-based heuristics to capture aesthetic images. In recent years, there has been a transformation in camera design from being purely physics-driven to increasingly data-driven and task-specific. In this paper, we present a framework to understand the building blocks of this nascent field of end-to-end design of camera hardware and algorithms. As part of this framework, we show how methods that exploit both physics and data have become prevalent in imaging and computer vision, underscoring a key trend that will continue to dominate the future of task-specific camera design. Finally, we share current barriers to progress in end-to-end design, and hypothesize how these barriers can be overcome.

Advanced Navigation Acquires Vai Photonics

Advanced Navigation, one of the world’s most ambitious innovators in AI robotics, and navigation technology has today announced the acquisition of Vai Photonics, a spin-out from The Australian National University (ANU) developing patented photonic sensors for precision navigation. 

Vai Photonics share a similar vision to provide technology to drive the autonomy revolution and will join Advanced Navigation to commercialise their research into exciting autonomous and robotic applications across land, air, sea and space.

“The technology Vai Photonics is developing will be of huge importance to the emerging autonomy revolution. The synergies, shared vision and collaborative potential we see between Vai Photonics and Advanced Navigation will enable us to be at the absolute forefront of robotic and autonomy driven technologies,” said Xavier Orr, CEO and co-founder of Advanced Navigation. 

“Photonic technology will be critical to the overall success, safety and reliability of these new systems. We look forward to sharing the next generation of autonomous navigation and robotic solutions with the global community.”

James Spollard, CTO and co-founder of Vai Photonics detailed the technology “Precision navigation when GPS is unavailable or unreliable is a major challenge in the development of autonomous systems. Our emerging photonic sensing technology will enable positioning and navigation that is orders of magnitude more stable and precise than existing solutions in these environments.

“By combining laser interferometry and electro-optics with advanced signal processing algorithms and real-time software, we can measure how fast a vehicle is moving in three dimensions. As a result, we can accurately measure how the vehicle is moving through the environment, and from this infer where the vehicle is located with great precision.”

The technology, which has been in development for over 15 years at ANU, will solve complex autonomy challenges across aerospace, automotive, weather, space exploration as well as railways and logistics.

Aircraft with an electric vertical takeoff and landing system such as flying taxis will greatly benefit from this technology. Landing and takeoff are often considered the most dangerous and expensive part of a flight route. Vai Photonics sensors will provide safe and reliable autonomous takeoff and landings under all conditions. 

Space travel and exploration is fraught with risks, vast complexity and enormous cost. This technology will bring massive benefits to space missions, helping to cement Advanced Navigation as the gold-standard for space-qualified navigation systems for space exploration. 

Professor Brian Schmidt, Vice-Chancellor of the Australian National University said “Vai Photonics is another great ANU example of how you take fundamental research – the type of thinking that pushes the boundaries of what we know – and turn it into products and technologies that power our lives.

“The work that underpins Vai Photonics’ advanced autonomous navigation systems stems from the search for elusive gravitational waves – ripples in space and time caused by massive cosmic events like black holes colliding.

Photonics magazine article on Pi Imaging SPAD array

Photonics magazine has a new article about Pi Imaging Technology's high resolution SPAD sensor array; some excerpts below.

As the performance capabilities and sophistication of these detectors have expanded, so too have their value and impact in applications ranging from astronomy to the life sciences.

As their name implies, single-photon avalanche diodes (SPADs) detect single particles of light, and they do so with picosecond precision. Single-pixel SPADs have found wide use in astronomy, flow cytometry, fluorescence lifetime imaging microscopy (FLIM), particle sizing, quantum computing, quantum key distribution, and single- molecule detection. Over the last 10 years, however, SPAD technology has evolved through the use of standard complementary metal-oxide-semiconductor (CMOS) technology. This paved the way for arrays and image sensor architectures that could increase the number of SPAD pixels in a compact and scalable way. 

Compared to single-pixel SPADs, arrays offer improved spatial resolution and signal-to-noise ratio (SNR). In confocal microscopy applications, for example, each pixel in an array acts as a virtual small pinhole with good lateral and axial resolution, while multiple pixels collect the signal of a virtual large pinhole.

Challenges: 

Early SPADs produced as single-point detectors in custom processes offered poor scalability. In 2003, researchers started using standard CMOS technology to build SPAD arrays. This change in design and production platform opened up the possibility to reliably produce high-pixel-count SPAD detectors, as well as invent and integrate new pixel circuity for quenching and recharging, time tagging, and photon-counting functions. Data handling in these devices ranged from simple SPAD pulse outputting to full digital signal processing.

Close collaboration between SPAD developers and CMOS fabs, however, has helped SPAD technology overcome many of its sensitivity and noise challenges by adding SPAD-specific layers into the semiconductor process flow, design innovations in SPAD guard rings, and enhanced fill factors made possible by microlenses. 

Applications:

Research on SPADs also focused on the technology’s potential in biomedical applications, such as Raman spectroscopy, FLIM, and positron emission tomography (PET).

FLIM [fluorescence lifetime imaging microscopy] benefits from the use of SPAD arrays, which allow faster imaging speeds by increasing the sustainable count rate via pixel parallelization. SPAD image sensors enhanced with time-gating functions can further expand the implementation of FLIM to nonconfocal microscopic modalities and thus establish FLIM in a broader range of potential applications, such as spatial multiplexed applications in a variety of biological disciplines including genomics, proteomics, and other “-omics” fields.

One additional application where SPAD technology is forging performance enhancements is high-speed imaging, in which image sensors typically suffer from low SNR. The shorter integration times in these operations lead to lower photon collection and pixel blur, while the faster readout speeds increase noise in the collected image. SPAD image sensors fully eliminate this noise to offer Poisson-maximized SNR.

About Pi Imaging:

Pi Imaging Technology is fundamentally changing the way we detect light. We do that by creating photon-counting arrays with the highest sensitivity and lowest noise.

We enable our partners to introduce innovative products. The end-users of these products perform cutting-edge science, develop better products and services in life science and quantum information.

Pi Imaging Technology bases its technology on 7 years of dedicated work at TU Delft and EPFL and 6 patent applications. The core of it is a single-photon avalanche diode (SPAD) designed in standard semiconductor technology. This enables our photon-counting arrays to have an unlimited number of pixels and adaptable architectures.

The sensor is designed for an optimal distance of 0-200 meters. The new chip offers new capabilities at a competitive price to significant growth markets for LiDAR systems, automotive ADAS, Metaverse AR/VR applications, Industry 4.0, and smart city/IOT, including smart traffic 3D vision systems.

The sensor is a result of five years of collaborative innovation by Newsight and its partners such as Fraunhofer and Tower-Jazz. The product offers unique features, including:

Newsight's patented enhanced Time-Of-Flight (eTOF) technology that is well demonstrated on the currently available NSI1000 sensor chip. This technology enables maximal flexibility using multi-sets of configurations, in-pixel accumulation, and a novel depth calculating method that does not require heavy calculations and expensive MCU.

Event aware unique circuit, which was developed as part of the Israeli smart imaging consortium (https://www.smartimagingiia.com/). The solution enables event driven imaging, while a unique circuit attached to each pixel makes it possible to broadcast only lines with pixels that were changed from a previous frame. This feature is specifically designed for smart-city enabled cameras and smart traffic solutions.

Multi-triangulation: a unique solution for industry 4.0 applications and measurement devices of 480 ultra-accurate depth points, down to micron accuracy for close 3D inspection of production rail objects.

Built in fusion, allowing the sensor to extract a full resolution B/W image together with a depth image from the same frame data, and making image and depth fusion trivial for systems developers.

Chip design using a standard CMOS image sensor process, with only two system power source requirements (1.8V, 3.3V), making it a low-power, easy to integrate, and affordable solution for mass markets.

Eyal Yatskan, Newsight CTO and Co-founder, noted: "Newsight has implemented significant, proven, and innovative ideas in this sensor and accelerated the capabilities of the solution to match the high-end requirements of our customers' target applications.

Original press release about Polycam's new app:

Polycam launches a 3D scanning app for the new iPhone 12 Pro models with a LiDAR sensor. The app allows users to rapidly create high quality, color 3D scans that can be used for 3D visualization and more. Because the scans are dimensionally accurate, they can be used to take measurements of virtually anything in the scan at once, rapidly speeding up workflows for many professionals such as architects and 3D designers. What is perhaps most impressive about Polycam is the speed -- scans which would have taken hours to process on a desktop without a LiDAR device can now be processed in seconds directly on an iPhone. 

As Chris Heinrich, the CEO of Polycam, puts it: "I've worked for years on 3D scanning with more conventional hardware, and what you can do on these LiDAR devices is literally 100x faster than what was possible before".

3D capture is a valuable tool for many industries, and Polycam is already seeing enthusiastic usage from architects, archaeologists, movie set designers and more, via an iPad Pro version that launched earlier this year. With the launch of the iPhone version, Heinrich expects to see adoption from many more users across a wider range of verticals. "Just as smartphones dramatically expanded the reach of photo and video", Heinrich says, "we expect these new LiDAR-enabled smartphones to dramatically increase the reach of 3D capture".

While the launch of the iPhone version is an important milestone, "this is just the beginning", says Heinrich. Many new features and improvements are in the pipeline, from enabling users to create even larger scans, improved scanning accuracy of smaller objects and a suite of 3D editing and AI-driven postprocessing tools to supercharge professional workflows that utilize 3D capture. 

Polycam is available to download on the App Store for the iPhone 12 Pro, 12 Pro Max, and the 2020 iPad Pro family. Sample 3D scans can be found on Sketchfab. Polycam was built by a small team of individuals with a passion for 3D capture, and deep experience in computer vision and 3D design.

[I am curious to know what the real-world challenges and limitations are. In particular, how much do the final results rely on lidar data vs. traditional "photogrammetry" that fuses multiple RGB images with minimal supervision from the lidar for, say, absolute scale? If you have an iPhone/iPad and get to try this app out, please share your thoughts in comments below! ---AI]

Will event-cameras dominate computer vision?

Dr. Ryad Benosman, a professor at University of Pittsburgh believes a huge shift is coming to how we capture and process images in computer vision applications. He predicts that event-based (or, more broadly, neuromorphic) vision sensors are going to dominate in the future.

Dr. Benosman will be a keynote speaker at this year's Embedded Vision Summit. 

EETimes published an interview with him; some excerpts below.

According to Benosman, until the image sensing paradigm is no longer useful, it holds back innovation in alternative technologies. The effect has been prolonged by the development of high–performance processors such as GPUs which delay the need to look for alternative solutions.

“Why are we using images for computer vision? That’s the million–dollar question to start with,” he said. “We have no reasons to use images, it’s just because there’s the momentum from history. Before even having cameras, images had momentum.”

Benosman argues, image camera–based techniques for computer vision are hugely inefficient. His analogy is the defense system of a medieval castle: guards positioned around the ramparts look in every direction for approaching enemies. A drummer plays a steady beat, and on each drumbeat, every guard shouts out what they see. Among all the shouting, how easy is it to hear the one guard who spots an enemy at the edge of a distant forest?

“People are burning so much energy, it’s occupying the entire computation power of the castle to defend itself,” Benosman said. If an interesting event is spotted, represented by the enemy in this analogy, “you’d have to go around and collect useless information, with people screaming all over the place, so the bandwidth is huge… and now imagine you have a complicated castle. All those people have to be heard.”

“Pixels can decide on their own what information they should send, instead of acquiring systematic information they can look for meaningful information — features,” he said. “That’s what makes the difference.”

This event–based approach can save a huge amount of power, and reduce latency, compared to systematic acquisition at a fixed frequency.

“You want something more adaptive, and that’s what that relative change [in event–based vision] gives you, an adaptive acquisition frequency,” he said. “When you look at the amplitude change, if something moves really fast, we get lots of samples. If something doesn’t change, you’ll get almost zero, so you’re adapting your frequency of acquisition based on the dynamics of the scene. That’s what it brings to the table. That’s why it’s a good design.”

He goes on to admit some of the key challenges that need to be addressed before neuromorphic vision becomes the dominant paradigm. He believes these challenges are surmountable.

“The problem is, once you increase the number of pixels, you get a deluge of data, because you’re still going super fast,” he said. “You can probably still process it in real time, but you’re getting too much relative change from too many pixels. That’s killing everybody right now, because they see the potential, but they don’t have the right processor to put behind it.” 

“[Today’s DVS] sensors are extremely fast, super low bandwidth, and have a high dynamic range so you can see indoors and outdoors,” Benosman said. “It’s the future. Will it take off? Absolutely!”

“Whoever can put the processor out there and offer the full stack will win, because it’ll be unbeatable,” he added.
