Optical receiver and related optical wireless transmission system

摘要

A light receiving element (13) receives a light signal (9). A light-permeable diffusive film (50) is disposed in front of the light receiving element (13). The light-permeable diffusive film (50) passes the light signal (9) at a predetermined transmission rate and diffuse the same. The light receiving element (13) and the light-permeable diffusive film (50) cooperatively constitute an optical receiver (61).
