Presentation Abstract

DigiLens’ unique electrically switchable holographic Bragg grating technology has been successfully applied to create a waveguide which effectively doubles the native resolution of a pico-projector in a near to eye AR waveguide display application. DigiLens’ switching technology, referred to as Transparent Resolution Expansion (T-REx), has been successfully applied to a DigiLens 50deg FoV waveguide. T-REx effective pixel doubling is an image wobulation technology achieved within DigiLens’ high MTF waveguides thereby providing a fully solid state solution (no mechanical vibration), with low electrical power characteristics, requiring minimal or no additional volume, and with high on time enabled by DigiLens’ high switch speed holographic nanomaterial system. During this webinar DigiLens’ switching grating technology and the application to T-REx will be introduced and described.
