Paper Abstract

Research and development project of an indoor laser radar communication system has been going on to establish one of wireless communication network environments. In the project, corner-reflecting laser communicating target `the Hyper Versatile (HV) target', is used for a free-space laser data communication with low power consumption and for accurate position detection of the target. Reflective-type Liquid Crystal Spatial Light Modulator (LC SLM) is a possible attractive component of the HV target to solve the above subjects. The indoor laser radar system should operate at eye-safe wavelength region, however, no infrared operating SLM has been released because conventional SLMs have been designed and manufactured only for visible light operations. In this paper, infrared (1.06 micrometers ) operating Parallel Aligned nematic Liquid-crystal Spatial Light Modulator (PAL- SLM) is described for an application for the indoor laser radar system. Characteristics of the SLM and numerical simulations for corner-reflecting operations are indicated.
