Sony Looks for Image Sensor Designers in Europe and USA

Nikkei reports that Sony intends to open more development centers in the U.S. and Europe "in an effort to make up for a scarcity of engineering talent in Japan."

Sony has a development center in the U.S. with dozens of engineers adapting designs to customer specifications. The company is contemplating to open a similar R&D center in Europe in two to three years. Sony also plans to add technical support stuff in China to work with the local customers.

The image sensor market is growing 9% a year to reach $19b in 2022, according to IC Insights. 80% of Sony's image sensor business depends on smartphones. The company aims to lower the smartphone exposure to 70% by 2025 by expanding into automotive and industrial applications.

In spite of controlling 50% of the image sensor market, an unnamed Sony executive says that the company "cannot secure enough talent by looking in Japan alone." Job openings in Japan are sometimes over four times the number of applicants. Design centers in USA and Europe might solve Sony talent hiring problems.

An earlier Nikkei article portrays the hiring problem as industry-wide in Japan: "There are 256 open positions for every 100 job seekers in the semiconductor industry in Japan, up from 52 per 100 in January 2014, according to staffing agency Recruit Career. That is higher than the average for all industries."

CSEM Develops Low Power Image Sensor for IoT

CSEM developed a fully autonomous portable camera that can be deployed quickly and easily via an adhesive patch or magnet, a world first. The Witness IOT camera consumes less than 1mW of power in active mode, fully covered by a flexible, high-efficiency photovoltaic cell with an adhesive surface. An HDR (120dB) CMOS sensor consuming less than 700uW @ 10 fps for 320x320 pixels allows triggering by scene–activity detection. The camera records fixed images at 1fps and stores them in flash memory for later USB readout.

Witness prototype measures 80 x 80 mm. Diameter of the camera button is 30 mm, its thickness is 4 mm. Forthcoming versions will thus include VGA resolution as well as embedded face recognition.

Enabling a range of applications from unattended surveillance and camera traps to wildlife observation, Witness perfectly embodies CSEM’s technological strategy,” enthuses Alain-Serge Porret, VP Integrated and Wireless Systems at the Swiss Research and Technology Organization. “We aim to deliver autonomous, low-energy-consuming devices combining both intelligence and efficiency.

CSEM publishes unusually high resolution pictures of the camera showing the sensor's fine layout details:

IEEE Spectrum on Image Sensor Damage by Lasers

As PZ pointed in comments, IEEE Spectrum publishes its own research on the camera damage by Aeye LiDAR at CES. The Spectrum article has quite a few interesting links, including a pointer to International Laser Display Association web page talking about the laser damage to the image sensors and referring to Fraunhofer open-access paper "Laser-induced damage threshold of camera sensors and micro-optoelectromechanical systems" by Bastian Schwarz, Gunnar Ritt, Michael Koerber, and Bernd Eberle published in Optical Engineering in 2017.

"The continuous development of laser systems toward more compact and efficient devices constitutes an increasing threat to electro-optical imaging sensors, such as complementary metal–oxide–semiconductors (CMOS) and charge-coupled devices. These types of electronic sensors are used in day-to-day life but also in military or civil security applications. In camera systems dedicated to specific tasks, micro-optoelectromechanical systems, such as a digital micromirror device (DMD), are part of the optical setup. In such systems, the DMD can be located at an intermediate focal plane of the optics and it is also susceptible to laser damage. The goal of our work is to enhance the knowledge of damaging effects on such devices exposed to laser light. The experimental setup for the investigation of laser-induced damage is described in detail. As laser sources, both pulsed lasers and continuous-wave (CW)-lasers are used. The laser-induced damage threshold is determined by the single-shot method by increasing the pulse energy from pulse to pulse or in the case of CW-lasers, by increasing the laser power. Furthermore, we investigate the morphology of laser-induced damage patterns and the dependence of the number of destructive device elements on the laser pulse energy or laser power. In addition to the destruction of single pixels, we observe aftereffects, such as persistent dead columns or rows of pixels in the sensor image."

The paper has an interesting experimental data on laser damage at 532nm wavelength:


Then, Fraunhofer researchers determine the laser energy density needed for each type of the damage:


Another SPIE paper studies the CIS damage by 1064nm laser pulses: "Damage effect on CMOS detector irradiated by single-pulse laser" by Feng Guo, Rongzhen Zhu, Ang Wang, and Xiang’ai Cheng from National Univ. of Defense Technology (China).

Camera Image Quality Benchmarking

Wiley publishes a book on image quality "Camera Image Quality Benchmarking" by Jonathan Phillips (Google) and Henrik Eliasson (Eclipse Optics).

"The authors show how to quantitatively compare image quality of cameras used for consumer photography. This book helps to fill a void in the literature by detailing the types of objective and subjective metrics that are fundamental to benchmarking still and video imaging devices. Specifically, the book provides an explanation of individual image quality attributes and how they manifest themselves to camera components and explores the key photographic still and video image quality metrics. The text also includes illustrative examples of benchmarking methods so that the practitioner can design a methodology appropriate to the photographic usage in consideration."


I'd guess part of the book content is exposed in Eclipse Optics blog at Medium, such as "Sharpness and Resolution" post:

Livox Announces $600 Automotive LiDAR

Spar3D: Livox starts shipping $600 LiDAR for autonomous vehicles and other applications:

"All Livox LiDAR sensors are low cost, high performance, highly reliable, compact in size, and mass-production ready. Specs (e.g., FOV, point density, and detection range) of different models are optimized for different application scenarios. In particular, the Mid-40 covers a circular FOV of 38.4 degrees with a detection range of up to 260 meters (for objects with reflectivity around 80%). Meanwhile, the Mid-100 combines three Mid-40 units internally to form an expansive horizontal FOV of approximately 100 degrees. Compared with the Mid-40, the Horizon has a similar measuring range but features a rectangular-shaped FOV that is 80 degrees horizontal and 25 degrees vertical, which is highly suitable for autonomous driving applications. The Horizon also delivers real-time point cloud data that is three times denser than the Mid series LiDAR sensors. As for the Tele-15, it features an ultra-long measuring range of 500 meters when reflectivity is above 80%. Even with 20% reflectivity, the measuring range is still up to 250 meters. In addition, the Tele-15 has a circular FOV of 15 degrees, which is narrower than the Mid-40, but delivers a point cloud that is 17 times denser. These key features enable the Tele-15 to see objects far ahead with great detail.

One major issue LiDAR manufacturers face is the need for extremely accurate laser/receiver alignments (less than 10 μm accuracy) within a spatial dimension of about 10cm or more. For most state-of-the-art LiDAR sensors that are currently available, these alignments are done manually by skilled personnel. Livox LiDAR sensors eliminate the need for this process by using unique scanning methods and the DL-Pack solution, which enables the mass production of Livox sensors.
"

The company is fairly open on its LiDAR performance. Mid-40/Mid-100 family offers:


Tele-15 has a narrow FoV and a longer range:


Horizon model has similar specs to Mid LiDARs:

Samsung Announces 20MP 0.8um Pixel Sensor for Slim Smartphones

BusinessWire: Samsung introduces its smallest high-resolution image sensor, the ISOCELL Slim 3T2, said to be the industry’s most compact 20MP image sensor at 1/3.4-inches. The 0.8μm-pixel ISOCELL Slim 3T2 is aimed to both front and back cameras in mid-range smartphones. The 1/3.4-inch 3T2 fits into a tiny module making more space in ‘hole-in or notch display’ designs.

The ISOCELL Slim 3T2 is our smallest and most versatile 20Mp image sensor that helps mobile device manufacturers bring differentiated consumer value not only in camera performance but also in features including hardware design,” said Jinhyun Kwon, VP of System LSI sensor marketing at Samsung Electronics. “As the demand for advanced imaging capabilities in mobile devices continue to grow, we will keep pushing the limits in image sensor technologies for richer user experiences.

When applied in rear-facing multi-camera settings for telephoto solutions, the 3T2 adopts an RGB color filter array instead of Tetracell CFA. The small size of the image sensor also reduces the height of the tele-camera module by around 7% when compared to Samsung’s 1/3-inch 20MP sensor. Compared to a 13MP sensor with the same module height, the 20Mp 3T2 retains 60% higher effective resolution at 10x digital zoom.

The Samsung ISOCELL Slim 3T2 is expected to be in mass production in Q1 2019.

Graphene-based SWIR G-Imager

Emberion, Graphenea, and AMO have been approved a European Innovation Council Fast Track to Innovation (FTI) project to help bring to the market the G-IMAGER, a graphene imager based on graphene-on-wafer technology. The G-Imager is a SWIR detector for applications in semiconductor inspection, sorting systems, spectroscopy hyperspectral imaging and surveillance. The projected market size for SWIR cameras in 2020 is around $1 billion.

The G-Imager will be based on the scientifically proven operation of a graphene channel coupled to nanocrystal light absorbers. The nanocrystals serve the function of strong light absorbers for high efficiency, whereas the graphene channel efficiently transports the generated charge to electrical contacts for detection. The benefits of G-Imager compared to other SWIR detectors, apart from the dramatic cost reduction, will be a lack of cooling requirements, low noise, large dynamic range, broad spectral range and scalable pixel size. These benefits guarantee quick market uptake of the product beyond the project duration, which is 24 months.

To bring G-Imager to the market, the project consortium will have to tackle challenges related to maturing the innovation. Namely, the production process yield for the detectors meeting a specified set of quality requirements must be guaranteed at a minimum of 85%, which is an industry standard. The technology readiness level must be raised to level 8, while scaling up the production process to meet volume requirements. Graphenea will scale up production of 200mm graphene-on-wafers to 10,000 wafers/year. A key project goal is integration into semiconductor production processes, such that G-Imager production is compatible with demanding requirements of the foundries where high-volume semiconductor device production takes place, like the foundry at AMO GmbH. AMO will develop a new “graphene device foundry service” to industrialize production of the photodetector. The SWIR detector production will be finalized at Emberion, where VGA resolution imager products will be made by depositing and patterning photosensitive materials on the graphene devices. Product finalization includes encapsulation, dicing and packaging the final imager products and integrating them into Emberion’s camera core products.

The consortium expects the project to assist in raising the cumulative net income of the consortium members to 60M€ in 4 years.

In a separate announcement, Emberion is to present a cost-competitive 512× 1 pixel VIS-SWIR linear array sensor for visible light to shortwave infrared (VIS-SWIR) detection at SPIE Photonics West in San Francisco on February 5-7, 2019. The sensor provides superior and consistent responsivity with very low noise over the broad (400 – 1800 nm) spectral range. The sensor is primarily designed for spectrometry applications. The sensor comprises an array of 25 × 500 µm2 pixels monolithically built on a tailor-made CMOS ROIC.

Beyond the linear array product introduced, Emberion will offer VGA imagers in late 2019. These VGA sensors cover the same VIS-SWIR spectral range (400-1800 nm wavelength) and are well suited for night and machine vision as well as hyperspectral imaging.

A 2017 Nature paper explains how the company's graphene imagers work:

OPPO also releases a new wide zone on-screen optical fingerprint recognition technology with recognition area up to 15 times of the current mainstream optical solution. The new optical fingerprint recognition includes two-finger simultaneous entry and authentication, achieving a security level 50,000 times of that of a single fingerprint.

Sofradir and ULIS to Invest €150M in French Nano 2022 Program

ALA News: Sofradir and its subsidiary ULIS announce their participation in the Nano 2022 initiative, which sees the Group invest €150M ($171M) over the period 2018-2022.

This announcement follows the European Commission’s approval on December 18, 2018 of the ‘Important Project of Common European Interest’ (IPCEI), a joint project by France, Germany, Italy and the UK to give €1.75 billion (approx. $2bn) in public support for research and innovation in microelectronics.

Nano 2022 will enable ULIS to develop the next generations of IR detectors to address trends in autonomous systems for smart buildings (workspace management, energy savings), road safety and in-cabin comfort of vehicles. It also enables Sofradir to develop the very large dimension IR detectors needed for space and astronomy observations as well as compact and light sensors that can be used in portable devices and on drones. Nano 2022 contributes to the funding of the pilot lines required for developing these technologies and products.


Update: IMVEurope: Sofradir and its subsidiary Ulis are investing €150M in the development of the next generations of IR detectors. David Billon-Lanfrey, director of strategy at Sofradir, says the company could potentially improve the performance of infrared sensors by up to 30% when the project concludes in 2022.

Sofradir aims to reduce the pixel pitch on its FPAs to enable higher resolution or, alternatively, reduce cost with smaller pixels. "We are working on our pixel structure so that we maintain the performance, even though the sensor area is getting smaller," David Billon-Lanfrey says. "We maintain the sensitivity of the pixel and we improve the resolution of the detector to improve the performance. The end result is a higher imaging range."

The second part of Sofradir’s R&D work is to increase the operating temperature of cooled FPAs from its currently -200°C.

Ulis, Sofradir’s subsidiary, will use the funding to target higher volume markets for its microbolometers.

Swiss Eye Tracking Startup Raises $1.9m

Swiss startup Eyeware develops 3D eye tracking software for depth sensing enabled consumer devices, such as Microsoft Kinect, Intel RealSense, Orbbec Astra, etc. How do they track gaze from low-resolution 3D images?

"Generally speaking: We require a low-resolution 3D pixel cloud of the face and eye regions and are agnostic to the underlying technology. It works as well for ToF sensors (i.e. non-RGB images). Our software uses that input to model the head pose and eye regions, providing the gaze vector in real-time."

Eyeware announces the closing of its seed financing round of 1.9M CHF ($1.9M USD). The seed round was led by High-Tech Gründerfonds (HTGF), in partnership with TRUMPF Venture GmbH, Swiss Startup Group, and Zurich Kantonalbank.

Eyeware is a spin-off of Idiap Research Institute and EPFL created in September 2016. Eyeware software can use automotive grade ToF cameras to estimate attention of drivers for in-cabin monitoring and infotainment systems. The capital will be used by the Eyeware team to bring the 3D eye tracking development kit ready for integration into consumer applications.
