LIGHT-FIELD VIRTUAL AND MIXED REALITY SYSTEM HAVING FOVEATED PROJECTION

摘要

The present disclosure concerns a light-field projection system, comprising a pin-light array (10) generating an incident light-field (100) illuminating an optical light modulator (20) for modulating the incident light-field (100) and projecting a plurality of modulated light-field components (110) along a projection axis (170); a first optical element (70, 32) configured for forming first pin-light images (31) in a first pin-light plane (30) and modulator images (114) in a modulator image plane (115); and a second optical element (40) defining an eye-box region (121) and for forming second pin-light images (120) in a second pin-light plane (124) within the eye-box (121); the first and second pin-light planes (30, 40) and the modulator image plane (115) being substantially perpendicular to the projection axis (170); the system further comprising at least one optical device (60, 61, 63, 64) at the first pin-light plane (30) and being configured for interacting with at least one of the modulated light-field components (110), spatially shifting the modulated light-field components in the modulator image plane (115). The light-field projection allows for foveated projection.
