The real-time holography system with a liquid-crystal television spatial light modular (LCTV- SLM) is presented. In the system, the LCTV-SLM is used as a phase hologram device. On the recording, the in-line holography method is used to reduce the spatial frequency of the fringe pattern of the hologram. The CCD camera detects the fringe pattern, and the fringe-pattern signal is transferred to the LCTV-SLM through the video-signal line. On the reconstruction process, the LCTV-SLM is illuminated by an He-Ne laser (633nm) and the spatial filtering technique is used to remove the zero and the higher-order diffracted light. Thus the holographic image of the real object can be observed continuously in real-time.
