Free space optics communication apparatus and free space optics communication system

Abstract

A free space optics communication apparatus which achieves high use efficiency of light and enables free control of the divergent angle of a light beam and the like is disclosed. The free space optics communication apparatus of the present invention has a light source which emits a light beam for performing wireless communication of information, and a minute mirror array unit which consists of a plurality of minute mirrors arranged in a matrix-like form and reflects the light beam emitted from the light source toward another apparatus. The apparatus also has a control unit which controls the directions of the individual minute mirrors constituting the minute mirror array unit independently. The control unit may be used to variably control the number of a plurality of mirror groups formed of a plurality of the minute mirrors in the minute mirror array unit.
