Abstract

Reflectivity modulating spatial optical communication has been researched using liquid crystal light modulator and corner-reflecting device for an adequate human-supporting information service environment. Conventional polymer dispersed liquid crystal light modulator had a subject of its response speed. In this paper, characteristics of a ferroelectric liquid crystal light modulator device are reported to improve its communicating data rate. A technique for higher data rate using a high-speed vision chip is also mentioned.
