摘要： Described are various embodiments of a light field device, pixel rendering method therefor, and vision perception system and method using same. One embodiment describes a method to adjust user perception of an image portion to be rendered via a set of pixels and a corresponding array of light field shaping elements (LFSE), the method comprising: projecting an adjusted image ray trace between a given pixel and a user pupil location to intersect an adjusted image location for a given perceived image depth given a direction of a light field emanated by the given pixel based on a given LFSE intersected thereby; upon the adjusted image ray trace intersecting a given image portion associated with the given perceived image depth, associating with the given pixel an adjusted image portion value designated for the adjusted image location based on the intersection; and rendering for each given pixel the adjusted image portion value associated therewith.

摘要： The embodiments relate to systems and methods for wavefront error (WFE) correction of a conformal optical component using a planar lens. The embodiments include a conformal optical component transmissive to electromagnetic radiation (EMR), which is propagated through the conformal optical component along a path axis. The conformal optical component is rotationally asymmetric about the path axis. A planar corrector lens is configured to correct a WFE of the conformal optical component. The planar corrector lens defines a lens axis. Accordingly, use of a single planar corrector lens for WFE correction of a conformal optical component reduces bulk and manufacturing complexity.

摘要： A method of dispersion compensation in an optical device is disclosed. The method may include identifying a first hologram grating vector of a grating medium of the optical device. The first hologram grating vector may correspond to a first wavelength of light. The method may include determining a probe hologram grating vector corresponding to a second wavelength of light different from the first wavelength of light. The method may also include determining a dispersion-compensated second hologram grating vector based at least in part on the probe hologram grating vector and the first hologram grating vector. A device for reflecting light is disclosed. The device may include a grating medium and a grating structure within the grating medium. The grating medium may include a dispersion compensated hologram.
