Alpha Pix is an ultra-low power spatial compute platform developed by Cogni Trax. AR displays are typically power hungry due to low efficiency of the [[waveguide]]s used. Alpha Pix is an ultra-low power spatial compute platform that overcomes these challenges. Alpha Pix is designed like a smartphone camera. It uses light from the ambient scene in the user’s surroundings thereby not requiring power needed for new photon generation and only consumes about 70mW of power. The Alpha Pix CMOS display panel is designed like a smartphone camera, where the imaging lens is integrated directly on the CMOS panel. Moreover, employing a [[catadioptric combiner]] allows a compact folded optical path enabling very high optical efficiency ranging from 25-75% thereby reducing power consumption.
