Abstract: A near-eye display system includes a transmissive display panel to display a near-eye light field frame comprising an array of elemental images. The transmissive display panel is configured to transmit light rays of the near-eye light field frame away from the user's eye and towards an array of curved beam splitters. The curved beam splitters collimate the transmitted light rays and reflect the collimated light rays back towards the transmissive display panel for passing to the user's eye.

Abstract: A near-eye display system includes a display panel to display a lightfield image comprising an array of elemental images and a lenslet array facing the display panel, the lenslet array comprising lenslets with spatially-varying prescriptions, such as different diameters, different focal lengths, and different asphere terms. The lenslet array further may be formed with a planar or non-planar substrate. The system further may include a distortion map comprising a set of transform matrices, each transform matrix configured to pre-distort a corresponding elemental image of a lightfield image so as to compensate for distortion expected to be introduced by a corresponding lenslet of the lenslet array, as well as a rendering component configured to modify the array of elemental images of a rendered lightfield using the distortion map to generate a modified lightfield image, and provide the modified lightfield image for display at the display panel for viewing via the lenslet array.
