The CGSS130 sensor is said to be 4 times more sensitive to NIR wavelengths than most other image sensor on the market today. Since the IR emitter consumes most of the power in face recognition and other 3D sensing applications, the use of the CGSS130 sensor will enable manufacturers to extend battery run-time in mobile devices. The sensor also creates the opportunity to implement face recognition in wearable devices and in other products which are powered by a very small battery, or to enable a new range of applications beyond face recognition as the increased sensitivity extends the measurement range for the same power budget.
Stephane Curral, EVP and GM at ams’ ISS division, says: “Following the announcement of ams’ partnership with SmartSens Technology earlier this year, we are delighted to announce the first 3D Active Stereo Vision (ASV) reference design based on the CGSS130 voltage-based NIR enhanced global shutter image sensor. The 1.3MP stacked BSI sensor offers the highest Quantum Efficiency at 940nm, ideally suited for battery-powered devices. By supplying all main parts of the 3D system (illumination, receiver, SW) ams enables superior system performance with lower costs and a faster time to market for its customers.“
Development of the CGSS130 has been accelerated by ams’ partnership with SmartSens Technology. The new sensor is available for sampling.
The CGSS130 has a QE up to 40% at 940nm, and up to 58% at 850nm. The stacked BSI process allows for a small footprint of just 3.8mm x 4.2mm and the GS pixel size of 2.7um.
The sensor produces monochrome images with an effective pixel array of 1080H × 1280V at a maximum frame rate of 120 fps. This high frame rate and global shutter operation produce clean images free of blur or other motion artifacts.
