Abstract: The present disclosure concerns a near-eye light-field display system comprising an emissive display (1), containing a plurality of display pixels (10, 12), each display pixel (10, 12) having color information and being individually addressable to be set inactive or active where it generate a light beam (111); and a lens array (14) comprising an array including a plurality of lenses (140) and configured to project the light beams (111) of the active display pixels (10, 12) to form a projection virtual pixel image (26). The projection pixel image (26) having color information and a position in space that are determined by the number of the active display pixels (10, 12) and their position on the emissive display (1). The present disclosure further concerns a method of projecting a projection virtual pixel using the near-eye light-field display system.

Abstract: A light-field projector comprising a light source configured to emit an incident light field illuminating a spatial light modulator (SLM) configured to display a reference SLM image pattern in an SLM plane. The reference SLM image pattern is configured to modulate the incident light field and generate a modulated light. A projection optic is configured to project the modulated light field along a reference optical axis such as to project a virtual image along the reference optical axis. The SLM is configured to display a corrected SLIM image pattern corresponding to the reference SLM image pattern shifted in the SLM plane, such that the virtual image is projected along an apparent projection axis that differs from the reference optical axis and such that the virtual image simulates at least an optical correction. The present disclosure further concerns a method for generating corrected virtual images by using the light field projector.
