LIGHT FIELD PROJECTOR BASED ON MOVABLE LED ARRAY AND MICROLENS ARRAY FOR USE IN HEAD -MOUNTED LIGHT -FIELD DISPLAY

摘要

A head-mounted light-field display system (HMD) includes two light-field projectors (LFPs), one per eye, each comprising a solid-state LED emitter array (SLEA) operatively coupled to a microlens array (MLA). The SLEA and the MLA are positioned so that light emitted from an LED of the SLEA reaches the eye through at most one microlens from the MLA. The HMD's LFP comprises a moveable solid-state LED emitter array coupled to a microlens array for close placement in front of an eye-without the need for any additional relay or coupling optics-wherein the LED emitter array physically moves with respect to the microlens array to mechanically multiplex the LED emitters to achieve resolution via mechanically multiplexing.
