Arxiv.org: Zurich University paper "Event-based Vision: A Survey" by G. Gallego, T. Delbruck, G. Orchard, C. Bartolozzi, B. Taba, A. Censi, S. Leutenegger, A. Davison, J. Conradt, K. Daniilidis, D. Scaramuzza compares different event-based cameras:

"Event cameras are bio-inspired sensors that work radically different from traditional cameras. Instead of capturing images at a fixed rate, they measure per-pixel brightness changes asynchronously. This results in a stream of events, which encode the time, location and sign of the brightness changes. Event cameras posses outstanding properties compared to traditional cameras: very high dynamic range (140 dB vs. 60 dB), high temporal resolution (in the order of microseconds), low power consumption, and do not suffer from motion blur. Hence, event cameras have a large potential for robotics and computer vision in challenging scenarios for traditional cameras, such as high speed and high dynamic range. However, novel methods are required to process the unconventional output of these sensors in order to unlock their potential. This paper provides a comprehensive overview of the emerging field of event-based vision, with a focus on the applications and the algorithms developed to unlock the outstanding properties of event cameras. We present event cameras from their working principle, the actual sensors that are available and the tasks that they have been used for, from low-level vision (feature detection and tracking, optic flow, etc.) to high-level vision (reconstruction, segmentation, recognition). We also discuss the techniques developed to process events, including learning-based techniques, as well as specialized processors for these novel sensors, such as spiking neural networks. Additionally, we highlight the challenges that remain to be tackled and the opportunities that lie ahead in the search for a more efficient, bio-inspired way for machines to perceive and interact with the world."

Semiconductor Engineering publishes a nice article on photoresist operation in EUV photolithography systems used in advanced processes. It shows how far the chemical imaging, the predecessor of image sensors, can go:

"In the early days of EUV development, supporters of the technology argued that it was “still based on photons,” as opposed to alternatives like electron beam lithography. While that’s technically true, even a casual glance at EUV optics shows that these photons interact with matter differently.

An incoming EUV photon has so much energy that it doesn’t interact with the molecular orbitals to any significant degree. John Petersen, principal scientist at Imec, explained that it ejects one of an atom’s core electrons.

...the photoelectron recombines with the material, ejecting another electron. This cascade of absorption/emission events, with energy dissipating at each step, continues until the electron energy drops below about 30 eV.

Once the electron energy is in the 10 to 20 eV range, Petersen said, researchers see the formation of quantized plasma oscillations, known as plasmons. The plasmons in turn create an electric field, with effects on further interactions that are not yet understood.

Only after energy falls below 5 to 10 eV, where electrons have quantum resonance with molecular orbitals, does the familiar resist chemistry of older technologies emerge. At this level, molecular structure and angular momentum drive further interactions."

Sony exhibition at Milan Design Week devoted to AI and robotics funture is based on the company's ToF and stereo vision technologies:

"Sony's leading image sensor technologies are used in the exhibits of "Affinity in Autonomy". Stereo cameras with back-illuminated Time-of-Flight image sensor and CMOS image sensor for sensing applications equipped with global shutter enable new interactive experiences by sensing conditions surrounding human and robotics.

Back-illuminated Time-of-Flight image sensor

With ToF technology, the distance to an object is measured by the time it takes for light from a light source to reach the object and reflect back to the sensor. ToF image sensors detect distance information for every pixel, resulting in highly accurate depth maps.
The new sensor which adopts back-illuminated CMOS image sensor architecture allows for more accurate detection of the reflected light because of improved sensor sensitivity.

CMOS image sensor for sensing applications equipped with global shutter function(IMX418)

The new product builds on the advantages of Sony's CMOS image sensor equipped with a global shutter function without focal plane distortion, with lower power consumption.

This product employs an angle of view with a 1:1 aspect ratio, which minimizes image information loss due to device tilt, whether the camera is mounted on the front, back, top, bottom, left or right of an HMD, drone, or autonomous robot."

KTH Royal Institute of Technology, Stockholm, Sweden publishes a PhD Thesis "Silicon Carbide High Temperature Photodetectors and Image Sensor" bu Shouben Hou.

"Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Driven by the objective of probing the high temperature surface of Venus (460 °C), this thesis develops SiC photodetectors and an image sensor for extremely high temperature functions. The devices and circuits are demonstrated through the procedure of layout design, in-house processing and characterizations on two batches.

The photodetectors developed in this thesis, including photodiodes with various mesa areas, a phototransistor and a phototransistor Darlington pair have stable characteristics in a wide temperature range (25 °C ~ 500 °C). The maximum operational temperature of the p-i-n photodiode (550 °C) is the highest recorded temperature accomplished ever by a photodiode. The optical responsivity of the photodetectors covers the spectrum from 220 nm to 380 nm, which is UV-only.

The SiC pixel sensor and image sensor developed in this thesis are pioneer works. The pixel sensor overcomes the challenge of monolithic integration of SiC photodiode and transistors by sharing the same epitaxial layers and topside contacts. The pixel sensor is characterized from 25 °C to 500 °C. The whole image sensor circuit has 256 (16 ×16) pixel sensors and one 8-bit counter together with two 4-to-16 decoders for row/column selection. The digital circuits are built by the standard logic gates selected from the TTL PDK. The image sensor has 1959 transistors in total. The function of the image sensor up to 400 °C is verified by taking basic photos of nonuniform UV illumination on the pixel sensor array."

Sony publishes an article "Perspectives from the creators of the image sensor “microcosm”" with interviews with the IMX586 CMOS sensor designers. Few quotes:

"With smartphone cameras getting more and more sophisticated in recent years, every company has been striving to make pixels smaller to meet the demand for more advanced cameras that are still small enough to fit in a phone. So, in order to stay ahead of the competition, we needed to develop even smaller pixels. With the IMX586, we were able to achieve a pixel size of 0.8 μm, which in turn made it possible to deliver a high resolution of 48 effective megapixels even on a compact sensor of 1/2 inch (8.0 mm diagonal).

Downsizing even 0.1 μm is, in fact, incredibly difficult... the trend of miniaturization is about to enter a turning point. That is, we will eventually reach the limit for simply making pixels smaller and face tradeoffs due to miniaturization.

...we can differentiate our product by curtailing noise so as to realize high sensitivity performance and pioneering new pixel structures and miniaturization.
In addition, at Sony, we have people nearby thinking about signal processing algorithms, and we have the manufacturing company within our Group. This proximity gives us an advantage in that it makes it easier for us to find ways to achieve overall optimization.

...for the IMX586, our algorithms played a big role in functions such as the high dynamic range (HDR) image composition, the array conversion processing for the Quad Bayer color filter array that achieves both high sensitivity and high resolution, and the phase difference detection entailed in high-speed autofocusing.

...since the pixel size of the IMX586 was a world-first at 0.8 μm, the basic development started at Nagasaki, the core manufacturing site for smartphone image sensor development. However, due to circumstances related to other product development, resources and production, we decided to develop and produce in Oita.

The team at Oita was, frankly, very surprised with that move as we did not believe that we had enough experience in image sensor development compared with other Sony technology centers, and so we never thought that we would be at the forefront of product development for such a challenging technology.

Secondly, it had only been a little while since the Oita Technology Center joined Sony Semiconductor Manufacturing, so there were many differences in development procedure and culture. For that reason, it was my mission to find a way to smoothly integrate the culture of the Oita plant with the culture of Sony Semiconductor Manufacturing. In the development of IMX586, the schedule was very tight, so there were challenges with unifying all the team members while working at the same time to meet the timeline.

The smaller the pixel, the more it becomes necessary to build the photodiodes in the depth direction of the silicon substrate. To do that, you need to use greater energy to inject impurities into the silicon.

Also, in the photolithography process, we use a thing called thick film resist. This time it was particularly difficult to address fluctuations in the imaging characteristics due to the change in shape of this thick film resist. We had to spend a lot of time improving processing reproducibility using the same equipment and uniformity in the wafer surface."

Swiss startup aiCTX announces a fully-asynchronous event-driven neuromorphic AI processor for low power, always-on, real-time applications. DynapCNN opens new possibilities for dynamic vision processing, bringing event-based vision applications to power-constrained devices for the first time.

DynapCNN is a 12mm^2 chip, fabricated in 22nm technology, housing over 1 million spiking neurons and 4 million programmable parameters, with a scalable architecture optimally suited for implementing Convolutional Neural Networks. It is a first of its kind ASIC that brings the power of machine learning and the efficiency of event-driven neuromorphic computation together in one device. DynapCNN is the most direct and power-efficient way of processing data generated by Event-Based and Dynamic Vision Sensors.

As a next-generation vision processing solution, DynapCNN is said to be 100–1000 times more power efficient than the state of the art, and delivers 10 times shorter latencies in real-time vision processing. Based on fully-asynchronous digital logic, the event-driven design of DynapCNN, together with custom IPs from aiCTX, allow it to perform ultra-low-power AI processing.

For real-time vision processing, almost all applications are for movement driven tasks (for example, gesture recognition; face detection/recognition; presence detection; movement tracking/recognition). Conventional image processing systems analyse video data on a frame by frame basis. “Even if nothing is changing in front of the camera, computation is performed on every frame,” explains Ning Qiao, CEO of aiCTX. “Unlike conventional frame-based approaches, our system delivers always-on vision processing with close to zero power consumption if there is no change in the picture. Any movement in the scene is processed using the sparse computing capabilities of the chip, which further reduces the dynamic power requirements.”

Those savings in energy mean that applications based on DynapCNN can be always-on, and crunch data locally on battery powered, portable devices. “This is something that is just not possible using standard approaches like traditional deep learning ASICs,” adds Qiao.

Computation in DynapCNN is triggered directly by changes in the visual scene, without using a high-speed clock. Moving objects give rise to sequences of events, which are processed immediately by the processor. Since there is no notion of frames, DynapCNN’s continuous computation enables ultra-low-latency of below 5ms. This represents at least a 10x improvement from the current deep learning solutions available in the market for real-time vision processing.

Sadique Sheik, a senior R&D engineer at aiCTX, explains why having their processors do the computation locally would be a cost and energy efficient solution, and would bring additional privacy benefits. “Providing IoT devices with local AI allows us to eliminate the energy used to send heavy sensory data to the cloud for processing. Since our chips do all that processing locally, there’s no need to send the video off the device. This is a strong move towards providing privacy and data protection for the end user.”

DynapCNN Development Kits will be available in Q3 2019.

ALA News: ULIS launches Atto640, a 60fps VGA 12um pixel thermal image sensor for reduced overall size and cost of the camera. The target market is commercial and defense applications, such as Thermal Weapon Sights (TWS), surveillance and handheld thermography cameras, as well as Personal Vision Systems (PVS), including portable monoculars and binoculars for consumer outdoor leisure, law enforcement and border control.

ULIS is adding a VGA format to its existing QVGA Atto320 to give camera manufacturers more choice in its 12 µm product range. The interest for camera makers is that, compared to 17 µm pixel pitch technology, the 12 µm pitch enables them to use smaller and lower cost optics.

Atto640 achieves its size advantage over competing models through its Wafer Level Packaging (WLP) technology, in which the detector window is directly bonded to the wafer, a technique enabling a significant reduction in the overall dimension of the sensor. Atto640’s footprint is half the size of ULIS’ Pico640-046 (17µm) model. Since Atto640 is designed with WLP, a batch-processing technique, it is suited to high-volume production.

Samples of Atto640 are currently available, with production ramp-up slated for the end of 2019. ULIS intends to further extend its 12µm product line up with larger resolution sensors.
