Abstract

PURPOSE:In light beam route or on the surfac eof the route, reflection frame having frame constant expressed by equation is provided with 45 deg. inclined against direction of light transport. By this, light wave which has mutually perpendicular skewed wave surface injected to the frame is separated and selected.
