Abstract

A matrix-addressed liquid crystal display device like LCTV-SLMs is one of the important devices for our electro-holography system. In this system, a CCD camera reads holographic interference fringe pattern and its signal is transferred to the LCTV-SLM by video signal line. The LCTV-SLM works as a dynamic holography device. A spatial filtering technique is applied to remove zero-order diffracted light on reconstruction. A comparison between amplitude-type and phase-type holograms and reconstruction by white light are described. The possibility of fine-pixel LCDs are also discussed.
