Abstract
To provide a free space optical communication apparatus with an increased efficiency of optical axis alignment. A free space optical communication apparatus () includes: light transmitting sections (); and an optical axis alignment section () configured to align an optical axis of each of the light transmitting sections () with a corresponding one of light receiving sections () included in a communication target. The optical axis alignment section () causes at least one of the light transmitting sections () to emit scan light () while varying an emitting direction, and aligns an optical axis of a light transmitting section () which is other than the at least one light transmitting section (), based on an emitting direction of the scan light () emitted from the at least one light transmitting section () and received by a corresponding one of the light receiving sections ().
