Image Enhancement of 3D Holographic Head-Up Display Using Multi-Constraints Angular Spectrum Algorithm

摘要

The digital holographic projection has been developed rapidly in recent years. It is expected to be applied to 3D displays like VR, AR, and HUD. However, the issues about the low image quality remain unsolved. In this paper, a new method called multi-constraints angular spectrum algorithm is proposed to enhance the image quality and is demonstrated in HUD.
