Pamtek presents 4 generations of its testing systems for camera modules:SiOnyx Camera Review
Image Sensors World Go to the original article...
DPReview publishes a review of SiOnyx Aurora night vision camera with Black Silicon sensor. The conclusion is:"Does the SiOnyx Aurora let me see things in the dark that I can't see with the unaided eye? Absolutely: the infrared sensitivity makes a big difference and, hence, my stress on the night vision capability of this device. The fact that you can also capture what you see is a plus. For me it was capturing Northern Lights, but I'm also looking forward to capturing surface lava flows in Hawaii, bioluminescence in Puerto Rico, as well as other phenomena around the world."

IEEE Journal of Selected Topics in Quantum Electronics publishes an open access paper "High-Performance Back-Illuminated Three-Dimensional Stacked Single-Photon Avalanche Diode Implemented in 45-nm CMOS Technology" by Myung-Jae Lee, Augusto Ronchini Ximenes, Preethi Padmanabhan, Tzu-Jui Wang, Kuo-Chin Huang, Yuichiro Yamashita, Dun-Nian Yaung, and Edoardo Charbon from EPFL, Delft University of Technology, and TSMC."We present a high-performance back-illuminated three-dimensional stacked single-photon avalanche diode (SPAD), which is implemented in 45-nm CMOS technology for the first time. The SPAD is based on a P + /Deep N-well junction with a circular shape, for which N-well is intentionally excluded to achieve a wide depletion region, thus enabling lower tunneling noise and better timing jitter as well as a higher photon detection efficiency and a wider spectrum. In order to prevent premature edge breakdown, a P-type guard ring is formed at the edge of the junction, and it is optimized to achieve a wider photon-sensitive area. In addition, metal-1 is used as a light reflector to improve the detection efficiency further in backside illumination. With the optimized 3-D stacked 45-nm CMOS technology for back-illuminated image sensors, the proposed SPAD achieves a dark count rate of 55.4 cps/μm 2 and a photon detection probability of 31.8% at 600 nm and over 5% in the 420-920 nm wavelength range. The jitter is 107.7 ps full width at half-maximum with negligible exponential diffusion tail at 2.5 V excess bias voltage at room temperature. To the best of our knowledge, these are the best results ever reported for any back-illuminated 3-D stacked SPAD technologies."

MDPI publishes a paper "A Back-Illuminated Time-of-Flight Image Sensor with SOI-Based Fully Depleted Detector Technology for LiDAR Application" by Sanggwon Lee, Keita Yasutomi, Ho Hai Nam, Masato Morita, and Shoji Kawahito from Shizuoka University."A back-illuminated time-of-flight (ToF) image sensor based on a 0.2 µm silicon-on-insulator (SOI) CMOS detector technology using fully-depleted substrate is developed for the light detection and ranging (LiDAR) applications. A fully-depleted 200 µm-thick bulk silicon is used for the higher quantum efficiency (QE) in a near-infrared (NIR) region. The developed SOI pixel structure has a 4-tapped charge modulator with a draining function to achieve a higher range resolution and to cancel background light signal. A distance is measured up to 27 m with a range resolution of 12 cm at the outdoor and average light power density is 150 mW/m2@30 m."

Neuro Vision spin-off fromAeye LiDAR Shows 1000m Track Detection, Raises $40m
Image Sensors World Go to the original article...
Techchrunch, Optics.org, VentureBeat: AEye raises a $40m in Series B. round led by Taiwania Capital, the investment firm created and backed by Taiwan’s National Development Council, and includes returning investors Kleiner Perkins, Intel Capital, Airbus Ventures and Tychee Partners.This brings the LiDAR startup’s total funding to about $61m. In the announcement, founder and CEO Luis Dussan said Taiwania’s investment is a strategic one and will give AEye more access to manufacturing, logistics and tech resources in Asia. AEye also plans to launch a new product at CES in January.
In tests monitored and validated by VSI Labs, a research company that focuses on autonomous-vehicle technology, AEye said that its iDAR sensor, which combines a solid-state lidar and high-resolution camera in one device, was able to detect and track a white color moving truck from one kilometer away. AEye claims that this is four to five times the distance other current lidar systems can detect.
In a press statement, AEye chief of staff Blair LaCorte said the company believes iDAR can potentially track moving objects, including trucks and drones, from 5km to 10km away.
