Abstract

We propose an aerial projection system for reconstruction of floating 3D images based on computer-generated image holograms (CGIHs). The proposed system consists of a spatial light modulator (SLM) and two concave mirrors. The SLM displays CGIHs, and a reconstructed 3D image is formed near the SLM plane. Because the two concave mirrors are set face to face, the floating image of the reconstructed 3D image can be projected at the hole of upper concave mirror. The system can reconstruct and project not only still 3D images but also 3D motion pictures by switching CGIHs.
