PURPOSE:To obtain a CCD sensor for optical communication which is capable of receiving received light and supplying the light to a reception sensor without weakening original intensity to be received by providing a through hole which is capable of passing at least the part of received light without receiving the light. CONSTITUTION:A CCD sensor 1 for optical communication is composed of light receiving elements 101 arranged in a grid-shape and a hole part 11 is provided at the center of a CCD sensor for optical communication. When this CCD sensor 1 for optical communication receives the light for communication from other communication satellites and a ground base station, etc., to be opposite parties, the part of this received light is capable of passing the hole part 11. When the received light passes the hole part 11 without being received at light receiving elements 101, it can be judged that the light reception is performed at an exact location without a deviation for the communication sensor, etc. When light reception is performed at the light receiving element 101 other than the hole part 11, this sensor performs a location detection in the same way as a conventional CCD sensor for optical communication and controls the antenna directions of the communication satellites from the detected deviation amount. |
