With the autopilot issues automotive, manufacturing, intelligent robots and other persistent fever Control Engineering Copyright , plays the role of intellectual machine eye 3D sensing technology much attention. Optical and electronic technology leader ─ optical path for Research and Innovation (Artilux) will be held in 2020 Consumer Electronics Show (CES), the exhibition titled “Explore” series of products, which is based on the world’s first silicon-germanium (GeSi , germanium-on-silicon) technology innovation broad spectrum 3D time of flight (the ToF) sensing technology, can reduce the potential for injury to the eye caused by the laser light, and increase the safety of more than 10 times , is a revolutionary innovation 3D sensor industry.

CES 2020 will be held January 7 to January 10 Las Vegas to carry out, the optical path for Research and Innovation exhibition for the first time this year, is expected to display the Explore series product includes logistics and machine vision RGB-D camera, and the first work in the long wavelength band 3D sensing system. This series will be available in the first quarter of 2020 formal mass production, will expand the application to the phone, the car with a laser radar system (LiDAR) and machine vision and other key areas. It is noteworthy that the optical path for Research and Innovation GeSi innovative technology developed in cooperation with TSMC, different from the current industry focus on 3D multi-sensor 850 nanometers and 940 nanometers two bands, the optical path for Research and Innovation Explore products for the world’s first ToF sensor can work in a 850 nm to 1550 nm band. Using a long wavelength band interference can effectively block the sun light sensor, to achieve the same effect in the sense for outdoor and indoor.

is further illustrated research record optical path, since the current mainstream 3D sensing solutions work most of light having a wavelength of 850 or 940 nm, a short wavelength sunlight for this band light will cause significant interference, so that the performance of 3D sensing outdoor greatly reduced; Further, if3D sensing system operating in a wavelength band from 1200 to 1400 Copyright Control Engineering , the human eye can bear security wavelength band of the laser power will be higher than 940 more than 10 times. Therefore, in accordance with existing international standards IEC 60825 specifications and related calculations, even if just a few centimeters between the laser and the human eye can still maintain a very high security. Research and Innovation optical path due to the use of unique and innovative technology GeSi Control Engineering Copyright , so that it can take the lead in developing a broad spectrum of flight time 3D sensing technology. Today, technology has GeSi by the International Solid-State Circuits Conference (International Solid-State Circuits Conference) favor, and related papers have been selected for ISSCC 2020, this innovative display technology by producing academic recognition, will be the future trend of 3D sensing technology.
