ADAS in China

ResearchInChina releases "ADAS and Autonomous Driving Industry Chain Report 2018 (II)– Automotive Vision" report.

"As a main sensor of ADAS autonomous driving era, the camera is widely used in lane detection, traffic sign recognition, obstacle monitoring, pedestrian recognition, fatigue driving monitoring, occupant monitoring, rear-view mirror replacement, reverse image, 360-degree panorama and so forth.

Camera installations amounted to 6.39 million units in the Chinese passenger car market in 2017, and the figure is expected to grow to 31.80 million units by 2021 with an AAGR of 49.3%, according to ResearchInChina.

Lens: Sunny Optical Technology, a leading automotive lens manufacturer in the world, shipped 18 million lenses in the first half of 2018. It has been a supplier of automotive lens for Magna, Continental, Delphi, Mobileye, Autoliv, Steel-mate, TTE, Panasonic and Fujitsu. The company also forays into the field of LiDAR optical parts.

Image sensor: ON Semiconductor and Sony are leaders, with the former sweeping a 44% share of the automotive image sensor market. Sony has continued to expand image sensor production capacity in recent years with heavy investment in automotive image sensor."

Film-Based Light Sensing Review

University of Toronto repo publishes a Nature paper from January 2017 "Solution-processed semiconductors for next-generation photodetectors" by F. Pelayo García de Arquer, Ardalan Armin, Paul Meredith, and Edward H. Sargent. " Efficient light detection is central to modern science and technology. Current photodetectors mainly use photodiodes based on crystalline inorganic elemental semiconductors, such as silicon, or compounds such as III–V semiconductors. Photodetectors made of solution-processed semiconductors — which include organic materials, metal-halide perovskites and quantum dots — have recently emerged as candidates for next-generation light sensing. They combine ease of processing, tailorable optoelectronic properties, facile integration with complementary metal–oxide–semiconductors, compatibility with flexible substrates and good performance. Here, we review the recent advances and the open challenges in the field of solution-processed photodetectors, examin...

Synaptics Under-Display Fingerprint Scanner Reverse Engineering

SystemPlus Consulting publishes a reverse engineering report of Synaptics’ under-display fingerprint scanner found inside the VIVO X21 UD Smartphone: " This scanner uses optical fingerprint technology that allows integration under the display. With a stainless steel support and two flexible printed circuit layers, the Synaptics fingerprint sensor’s dimensions are 6.46 mm x 9.09 mm, with an application specific integrated circuit (ASIC) driver in the flex module. This image sensor is also assembled with a glass substrate where filters are deposited. The sensor has a resolution of 30,625 pixels, with a pixel density of 777ppi. The module’s light source is providing by the OLED display glasses. The fingerprint module uses a collimator layer corresponding to the layers directly deposited on the die sensor and composed of organic, metallic and silicon layers. This only allows light rays reflected at normal incidence to the collimator filter layer to pass through and reach the optical ...

LED Flicker Tutorial Paper

IE 2008 publishes a paper " LED flicker: Root cause, impact and measurement for automotive imaging applications " by Brian Deegan, Valeo Vision Systems. " In recent years, the use of LED lighting has become widespread in the automotive environment, largely because of their high energy efficiency, reliability, and low maintenance costs. There has also been a concurrent increase in the use and complexity of automotive camera systems. To a large extent, LED lighting and automotive camera technology evolved separately and independently. As the use of both technologies has increased, it has become clear that LED lighting poses significant challenges for automotive imaging i.e. so-called "LED flicker". LED flicker is an artifact observed in digital imaging where an imaged light source appears to flicker, even though the light source appears constant to a human observer. This paper defines the root cause and manifestations of LED flicker. It defines the use cases wher...
