Abstract
New type mobile multi-cannel communication and movie projection systems are proposed and discussion.
Main salient charactrristucs are high speed, high density with high for multi-cannel optical communication system,optical total reflection and retro-reflection charestristics of corner cube is commented. For high density optical high speed projection, MEMS application is described compaired well known Liquid christel projector is described compaired with known Loquid christal one projecter and ceramic projecter systems.
Industrial applications are also proposed such as mobile ITS and any vehicle appliations.
