Cogni Trax is a company that has developed hard edge occlusion for optical see through displays, called Alpha Pix. It is based in Silicon Valley.
It is a display photonics startup company focusing on unique visual experience for AR smart glasses applications.
Their technology uses at least one SLM and quarter wave plate to cancel out light.[1]
Alpha Pix
The Alpha Pix platform uses a catadioptric combiner in a thin form factor for AR smart glasses. Alpha Pix controls per-pixel transparency in the virtual image plane, so it is possible to display virtual imagery in a black color. The black imagery can hard-edge occlude physical objects in the real background scene, making the generated black content visible even in direct sun-lit environments.
Alpha Pix uses less power than waveguide-based augmented reality displays, but it does not work in the dark and it only displays the color black. It uses light from the ambient scene in the user’s surroundings, so it doesn't require power for new photon generation. In total, it 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. Alpha Pix uses a catadioptric combiner, which allows a compact folded optical path that enables very high optical efficiency between 25 percent and 75 percent.
Alpha Pix technology is patented in U.S. patent US10983355B2.
