Abstract

Holography is one of the most promising candidates to realize a fully realistic 3D video communication system. We propose a hologram generation method by using depth maps of real scenes. In this study, we employed a static laser scanner and captured a depth map of real objects at 0.4mm resolution. Then, a Fresnel hologram was calculated off-line on a computer. We used two types of SLMs. One is 12micron transparent LCD, and the other is 10.4micron pixel reflective LCD panel. By irradiating He-Ne laser to the hologram, we observed 3D real object images are reconstructed in the space with approx. 5cm of depth range.
