Automatic synthesis of holographic stereograms with ray‐traced image data

An automatic synthesizing method of holographic stereograms (HSs) has been studied for computer‐graphic images, and experimental results of image reconstruction have been presented. In the synthesis of the HSs, raytraced image data of 180 frames were generated, changing a viewpoint. Then these data were recorded on a holographic film of about 70 mm x 300 mm using a liquid crystal television panel as a spatial light modulator. The fabrication time of one HS was about 50 min. In image reconstruction with a 5‐mW He‐Ne laser, it has been possible to display three‐dimensional images which have a good parallax effect.
