Full-color holographic Maxwellian near-eye display with extended eyebox

Recently, the development of augmented reality (AR)/virtual reality (VR) has brought new life to holographic display. Holographic Maxwellian display technology, also known as holographic retinal projection display (RPD), is considered as a promising AR near-eye display technology. It can provide consistently sharp two-dimensional images within a range of depth of field without being affected by human eye focusing. Several recent works of holographic Maxwellian near-eye display are introduced. Firstly, we have proposed a hybrid holographic Maxwellian near-eye display based on spherical wave and plane wave reconstruction to extend the depth of field. Secondly, we have proposed a lensless full-color holographic Maxwellian near-eye display with horizontal eyebox expansion using a single spatial light modulator (SLM). Thirdly, we have proposed a conjugate wavefront encoding method to efficiently expand the eyebox for the holographic Maxwellian near-eye display.
