Abstract
Briefly, in accordance with one or more embodiments, a buried numerical aperture expander may be utilized to provide a head-up or virtual display at a larger field of view without requiring a larger amount of space, larger sized display, or larger sized optics. The buried numerical aperture expander is capable of selectively reflecting light emanating from a display such that the reflected light is expanded into a larger field of view, while simultaneously allowing other light to be transmitted through the buried numerical aperture expander without expansion so that the buried numerical aperture expander may be deployed in conjunction with a windshield or window without adversely affecting the ability to see through buried numerical aperture expander.
