Multi-focal augmented reality head-up display system and method

Abstract

The present disclosure relates to a multi-focal head-up display (MHUD) system and method to solve a visual fatigue problem generated in a vehicle head-up display and implement an augmented reality (AR) function. The present disclosure provides a multi-focal augmented reality head-up display (MHUD) system including an image projector which generates and emits a plurality of beams, an optical device which guides the plurality of beams emitted from the image projector to individual paths, a polarization control device which controls polarization states of the plurality of beams incident from the optical device, and a plurality of holographic optical elements (HOEs) which receives the plurality of beams emitted from the polarization control device to project a virtual image plane at different focal distances.

Dependencies are inferred from the claim text.
