Abstract: An optical communication device, for performing communication between spatially separated points by using one or more laser beams, includes an angle correction device that corrects a direction of a light receiving system and an emission optical axis correction device, in which an angle error which is not corrected by the angle correction device is detected by a light receiving angle detection device, and the emission optical axis correction device is controlled according to a detected error amount, and an emission optical axis is corrected.

Abstract: A communication device includes an interleaving unit that determines an interleaving length of transmit data to be transmitted through free-space optical communication, and interleaves the transmit data based on the determined interleaving length, and a shaping unit that shapes the interleaved transmit data so as to make the interleaving length detectable on a receiving side of the free-space optical communication.
