An interactive holographic projection system that uses a hand-drawn interface with a consumer CPU

Abstract Holography is a promising technology for photo-realistic three-dimensional (3D) displays because of its ability to replay the light reflected from an object using a spatial light modulator (SLM). However, the enormous computational requirements for calculating computer-generated holograms (...
