    摘要： 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.

    摘要： Briefly, in accordance with one or more embodiments, an optical relay comprises a partially-reflective-coated Fresnel lens or similar low-profile lens such as a diffractive lens or a holographic lens having a first index of refraction and a filler medium having a second index of refraction and being disposed adjacent to the Fresnel lens. The optical relay enables the optical power of the Fresnel or similar low-profile lens embedded within the two layers to influence a beam that is reflected from the optical relay while allowing transmitted light to experience little or no influence from the embedded lens.

    摘要： Briefly, in accordance with one or more embodiments, scanned beam projector may comprise a light source, a scan drive and a scanning platform to project an image onto a projection surface. The scan drive circuit is capable of at least partially correcting distortion in the projected image by varying an amplitude of the scan drive signal to at least partially compensate for the distortion in the projected image.
