Alpha Pix is an ultra-low power spatial compute platform developed by Cogni Trax. While VR headsets are bulky, slow and heavy, the AR displays are power hungry due to low efficiency of the Waveguides 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.

Cogni Trax is based in Silicon Valley. It is a display photonics startup company focusing on unique visual experience for AR smart glasses applications. Their Alpha Pix platform demonstrates a world first catadioptric combiner in a thin form factor for AR smart glasses. Thanks to Cogni Trax’ patented Alpha Pix technology that controls per-pixel transparency in the virtual image plane, virtual objects and holograms in a black color can now be realized. These black holograms can hard-edge occlude physical objects in the real background scene, making content visibility possible even in direct sun-lit environments.
