Abstract(in English) In order to realize information support service system in a location in short-distance and closed space, multiple and simultaneous information providing technique using the spatial optical communication based on the computer-generated hologram (CGH) and an infrared camera with LED illuminator is introduced for indoor-users with a compact battery-less information terminal. User's position is detected by a corner-reflected light spot on the infrared camera. Directed infrared data beam was generated by a CGH pattern on a PAL-SLM. Directed data beam was generated by CGH on a 1.48μm PAL-SLM using the recognized position. Experimental results of enhancement of deflected angle and real time tracking of a reflector are also described.
