Abstract

A novel VGA, 10 micron pixel, multi-functional InGaAs imager is presented. This sensor combines standard imaging for daylight use and high-gain mode for low light level use with event-based imaging and laser multi-spot sensing. The fast imaging modes go up to 1.6 kHz for full-frame and are sensitive in the Visible to SWIR band (600-1700nm). The event-based mode and the laser multi-spot mode are able to operate simultaneously to the image with their output provided in a separate video channel. The event mode is responsive to image variations only, enabling to capture landscape events at a rate that is more than x10 faster than the standard imaging. The laser multi-spot mode responds to multiple laser illumination at a fast rate that enables to recognize the presence of laser spot as well as its pulse repetition frequency. This work elaborates on the multi-functional architecture, demonstrates its key features, and shows first measurements of the ROIC and sensor.
