Abstract
Our several recent works on holographic retinal projection display (RPD) are introduced here. First, a lensless dynamic full-color holographic RPD with horizontal eyebox expansion using a single spatial light modulator (SLM) was demonstrated.Secondly, we propose to efficiently extend the eyebox of holographic Maxwellian near-eye display by encoding the conjugate wavefront as the multiplication of plane wave phase with the target image. Thirdly, a holographic super multi-view (SMV) RPD is proposed to provide depth cues for a monocular vision.Fourthly, a multi-channel holographic RPD was proposed, which can provide multi-channel image sources simultaneously, thus greatly increasing the information content.The proposed method provides a good prospect that the future AR glasses can play dozens of video channels in parallel, and the user can switch among channels freely and efficiently just through a simple eye rotation.
