Abstract
A near-to-eye optical system includes an optically transmissive substrate having a see-through display region and a repeating pattern of diffraction elements. The repeating pattern of diffraction elements is disposed across the see-through display region of the optically transmissive substrate and organized into a reflective diffraction grating that bends and focuses computer generated image (“CGI”) light impingent upon the reflective diffraction grating. The see-through display region is at least partially transmissive to external ambient light impingent upon an exterior side of the optically transmissive substrate and at least partially reflective to the CGI light impingent upon an interior side of the optically transmissive substrate opposite the exterior side.
