Paper Abstract

In the past, the transmission of holograms via television was executed but no holographic TV was realized because there was no suitable recording material. Now a 3-D TV is expected, and recent research on real time holography using a high-resolution liquid crystal device (LCD) is active. In this research we consider the possibility of holographic television and construct the best system possible with commercially available devices. First, holographic fringe patterns for moving objects are made with TV cameras. Then the hologram pattern is transformed to electrical signals and transmitted within the TV frequency band. Finally, the hologram fringe pattern is displayed on the LCD and the 3-D image is reconstructed. In this research, we used the moving object and considered its characteristics. The filtering method was used to improve S/N of the reconstructed image and to extend the viewing angle.
