Paper Abstract

We present a holographic method for augmented reality near-eye display system based on the projection of a digital amplitude-only computer-generated hologram (AO-CGH) on a DMD. The operating principle is based upon Fresnel holography and spatial light modulator encodings. The resultant system can display a high-resolution 3D image with accurate depth cues. Furthermore, we fully utilize the diffraction bandwidth of the hologram by eliminating the DC and conjugation noise, providing a simple solution to a long-standing problem in holographic displays. As a result, our system is low cost and compact, lending credence to consumer AR applications.
