PCH-EM Algorithm for DSERN characterization

Hendrickson et al. have posted two new pre-prints on deep sub-electron read noise (DSERN) characterization. This new algorithm called PCH-EM is used to extract key performance parameters of sensors with sub-electron read noise through a custom implementation of the Expectation Maximization (EM) algorithm. It shows a dramatic improvement over the traditional Photon Transfer (PT) method in the sub-electron noise regime. The authors have some extensions and improvements of the method coming soon as well.

The first pre-print titled "Photon Counting Histogram Expectation Maximization Algorithm for Characterization of Deep Sub-Electron Read Noise Sensors" presents the theory behind their approach.

Abstract: We develop a novel algorithm for characterizing Deep Sub-Electron Read Noise (DSERN) image sensors. This algorithm is able to simultaneously compute maximum likelihood estimates of quanta exposure, conversion gain, bias, and read noise of DSERN pixels from a single sample of data with less uncertainty than the traditional photon transfer method. Methods for estimating the starting point of the algorithm are also provided to allow for automated analysis. Demonstration through Monte Carlo numerical experiments are carried out to show the effectiveness of the proposed technique. In support of the reproducible research effort, all of the simulation and analysis tools developed are available on the MathWorks file exchange.

The second pre-print titled "Experimental Verification of PCH-EM Algorithm for Characterizing DSERN Image Sensors" presents an application of the PCH-EM algorithm to quanta image sensors.

Abstract: The Photon Counting Histogram Expectation Maximization (PCH-EM) algorithm has recently been reported as a candidate method for the characterization of Deep Sub-Electron Read Noise (DSERN) image sensors. This work describes a comprehensive demonstration of the PCH-EM algorithm applied to a DSERN capable quanta image sensor. The results show that PCH-EM is able to characterize DSERN pixels for a large span of quanta exposure and read noise values. The per-pixel characterization results of the sensor are combined with the proposed Photon Counting Distribution (PCD) model to demonstrate the ability of PCH-EM to predict the ensemble distribution of the device. The agreement between experimental observations and model predictions demonstrates both the applicability of the PCD model in the DSERN regime as well as the ability of the PCH-EM algorithm to accurately estimate the underlying model parameters.

Semi Conductor Devices (SCD), a manufacturer of uncooled infrared detectors and high-power laser diodes, has launched a new SWIR detector, the Swift-El.

The Swift-El is designed as a very low Size Weight and Power (SWaP) and low-cost VGA format 10-micron pitch detector.

According to SCD, it is the world's first SWIR detector integrating event-based imaging capabilities, making it a 'revolutionary' addition to the defence and industrial sectors.

Its advanced FPA level detection capabilities enable tactical forces to detect multiple laser sources, laser-spots, Hostile Fire Indication (HFI), and much more.

Its ROIC imager technology offers two parallel video channels in one sensor - a standard imaging SWIR video channel, and a very high frame event imaging channel.

The Swift-El offers SWIR imaging that supports day and low-light scenarios, enabling 24/7 situational awareness, better atmospheric penetration, and a low-cost SWIR image for tactical applications. Furthermore, its event-based imaging channel provides advanced capabilities, such as laser event spot detections, multi-laser spot LST capabilities, and SWIR event-based imaging, broadening the scope of target detection and classification.

The Swift-El also opens up new capacities for machine vision applications in fields such as production line sorting machines, smart agriculture, and more, where analysis of high-level SWIR images is required for automatic machine decision-making. The Swift-El enables a full frame rate of more than 1,200Hz, which is essential for machine vision and machine AI algorithms.

Kobi Zaushnizer, CEO of SCD, elaborates on the company's latest innovation: "SCD is proud to launch the Swift-El - the world's first SWIR imager to enable event-based imaging. This new product is part of our value to be ‘always a step ahead’ and our promise to our customers to ‘be the first to see’. The Swift-El event-based imaging enables the next generation of AI-based systems, offering the multi-domain battlespace multi-spectral infrared imaging for better situational awareness, advanced automatic target detection and calcifications, and target handoff across platforms and forces, while increasing warrior lethality. It also enables HFI detection, and all of this at a price point that makes it possible for SWIR cameras to be integrated into high-distribution applications, such as weapon sights and clip-ons, drones, man-portable target designators, and more. The advanced detector is already being delivered to initial customers around the world, and we expect to see a significant production ramp-up in the coming months."

Lynred breaks ground on new €85M industrial site for infrared technologies

 Named Campus, Lynred’s new state-of-the-art industrial facility will meet growing market demand for advanced infrared technologies, notably for automotive sector, whilst bolstering French industrial sovereignty in field
 
Company’s production capacity set to undergo 50% increase by 2025; 100% by 2030
 
Grenoble, France, May 10, 2023 – Lynred, a leading global provider of high-quality infrared detectors for the aerospace, defense and commercial markets, today announces breaking ground on its new €85 million ($93.7M) industrial site to produce state-of-the-art infrared technologies. This is the biggest construction investment that the company has undertaken since it began manufacturing in 1986.
 
The project is financed by loans from the CIC bank and Bpifrance.
 
Lynred will double its current cleanroom footprint, totaling 8,200 m2 (88,264 ft2), primarily to meet two strategic objectives:
 Obtain an optimal cleanroom cleanliness classification for its new high-performance products (hybrid detectors)
 Increase the production capacity for its more compact industrial products (bolometers) used in multiple fields, including the automotive industry
This substantial investment will consolidate Lynred’s positioning as European market leader in infrared detection. It enables the company to play a key role within the European defense industrial and technological base, innately woven into strengthening French and European forces, for whom infrared detection is hugely important. With this, Lynred takes a step up in responding to the French government’s call to reorient European industry towards a ‘rearmament economy’ (FR).
 
To mark the ground breaking on May 10, Jean-François Delepau, chairman of Lynred, planted a holm oak tree.
 
“I am delighted to see our state-of-the-art industrial site come to life, consolidating our position as the second largest infrared detector manufacturer in the world. This will enable us to respond to growing market demand for next-generation infrared technologies, including in the automotive sector. It will allow us to contribute to bolstering France’s industrial sovereignty and, more generally, to improve our overall industrial performance. Above all, I wish to thank the Lynred teams involved in this major undertaking, as well as all our partners who have supported us, in particular our shareholders, Thales and Safran. Lynred is embarking on a new strategic pathway, both in terms of technology and dynamic growth,” said Mr Delepau.
 
The buildings are due for completion in the first trimester of 2025 and the site will be fully operational by the following October. This state-of-the-art industrial facility will comprise 8,200 m2 (88,264 ft2) of interconnected cleanrooms (twice the current surface area), 3,400 m2 (36,600ft2) of laboratories, a 2,300 m2 (24,756 ft2) logistics area, and a tertiary and technical area measuring 10,800 m2 (11,625 ft2).
 
Lynred is looking to increase its production capacity by 50% by 2025, in particular for its bolometer products, with a view to doubling capacity by 2030.
 
With these new cleanrooms the company will house all of its French production lines in a single location. This will enable synergies amongst core competencies and optimize production flows.
 
The new buildings will be located on the current Lynred site in Veurey-Voroize, situated within the Grenoble area. They have been designed to ensure optimized energy management and environmental performance: even with 13,600 m2 (146,400 ft2) under construction, the volume of permeable surface will increase. The company will decrease its carbon footprint by 33% and will install 1,800 m2 (19,375 ft2) of solar panels. Moreover, the site will accommodate an additional 320 trees and more than 100 charging stations for electric vehicles (cars and bicycles) will be put in place, with more cycle parking added.

Review article on figures of merit of 2D photodetectors

A review article in Nature Communications by Wang et al. (Shanghai Institute of Technical Physics) discusses techniques for characterizing 2D photodetectors.

Full paper: https://www.nature.com/articles/s41467-023-37635-1

Abstract: Photodetectors based on two-dimensional (2D) materials have been the focus of intensive research and development over the past decade. However, a gap has long persisted between fundamental research and mature applications. One of the main reasons behind this gap has been the lack of a practical and unified approach for the characterization of their figures of merit, which should be compatible with the traditional performance evaluation system of photodetectors. This is essential to determine the degree of compatibility of laboratory prototypes with industrial technologies. Here we propose general guidelines for the characterization of the figures of merit of 2D photodetectors and analyze common situations when the specific detectivity, responsivity, dark current, and speed can be misestimated. Our guidelines should help improve the standardization and industrial compatibility of 2D photodetectors.

tinyML Summit 2023: Deploying Visual AI Solutions in the Retail Industry

Mark HANSON , VP of Technology and Business Innovation, Sony Semiconductor Solutions of America
An image sensor with AI-processing capability is a novel architecture that is pushing vision AI closer to the edge to enable applications at scale. Today many AI applications stall in the PoC stage and never reach commercial deployment to solve real-world problems because existing systems lack simplicity, flexibility, affordability, and commercial-grade reliability. We’ll investigate why the retail industry struggles to keep track of stock on its retail shelves while relying on retail employees to manually monitor stock and how our (AITRIOS) vision AI application for on-shelf-availability can eliminate complexity and inefficiency at scale.

Paper on 8-tap ToF Sensor

Miyazawa et al. from Shizuoka University in Japan recently published an article titled "A Time-of-Flight Image Sensor Using 8-Tap P-N Junction Demodulator Pixels" in the MDPI Sensors journal.

[Open access: https://www.mdpi.com/1424-8220/23/8/3987]

Abstract:
This paper presents a time-of-flight image sensor based on 8-Tap P-N junction demodulator (PND) pixels, which is designed for hybrid-type short-pulse (SP)-based ToF measurements under strong ambient light. The 8-tap demodulator implemented with multiple p-n junctions used for modulating the electric potential to transfer photoelectrons to eight charge-sensing nodes and charge drains has an advantage of high-speed demodulation in large photosensitive areas. The ToF image sensor implemented using 0.11 µm CIS technology, consisting of an 120 (H) × 60 (V) image array of the 8-tap PND pixels, successfully works with eight consecutive time-gating windows with the gating width of 10 ns and demonstrates for the first time that long-range (>10 m) ToF measurements under high ambient light are realized using single-frame signals only, which is essential for motion-artifact-free ToF measurements. This paper also presents an improved depth-adaptive time-gating-number assignment (DATA) technique for extending the depth range while having ambient-light canceling capability and a nonlinearity error correction technique. By applying these techniques to the implemented image sensor chip, hybrid-type single-frame ToF measurements with depth precision of maximally 16.4 cm (1.4% of the maximum range) and the maximum non-linearity error of 0.6% for the full-scale depth range of 1.0–11.5 m and operations under direct-sunlight-level ambient light (80 klux) have been realized. The depth linearity achieved in this work is 2.5 times better than that of the state-of-the-art 4-tap hybrid-type ToF image sensor.

Another article on Panasonic's organic image sensor

Panasonic’s Decade-Old Organic CMOS Sensor is Still Years Away

As a quick reminder, Panasonic's patented technology relies on an organic thin-film photo-conversion material in lieu of the conventional technique where a silicon photodiode converts light into electrical charge.

Some excerpts from the article are below.

 

... it has been nearly 10 years since the company first announced it was working on this new sensor and in that time, a lot has changed. The previously exciting low light capabilities have since been realized by other sensors...

[In an updated announcement last year Panasonic suggested ...] 8K resolution while retaining those dynamic range promises and would do so at high framerates. More recently, Panasonic explained that the sensor would also feature what is known as “reduced crosstalk,” which basically means that the red, green, and blue pixels of the sensor collect only their intended color and that light, regardless of type and color cast, and won’t spill across each pixel. This results in better color reproduction.

...

Basically, it’s very difficult to get excited about Panasonic’s organic CMOS, and that would be the case even if it was coming to market this year.

...

There are those who have been saying Sigma’s Foveon sensor is stuck in “development hell,” but Panasonic easily has it beat with its organic CMOS.
