Abstract
Parallel aligned liquid crystal-spatial light modulator (PAL-SLM) has been applied to an optical interconnection system by a CGH technique. In the system, the PAL-SLM is expected to have electrically addressed capability. We have developed a CRT coupled PAL-SLM that can be electrically addressed. For that purpose, the CRT have been designed and evaluated on a fluorescence spectrum and an afterglow time of a phosphor to suit PAL-SLM features. And we have also evaluated two coupling methods between the CRT and the PAL- SLM ; one is a relay lens coupling method and the other is a fiber optic plate (FOP) coupling method. Consequently, it can be concluded that a combination of a red phosphor with a long afterglow time and the FOP coupling method is suitable for the CGH application. We can get a fine and noiseless CGH reconstruction image by using this module.
