Abstract
A receiver for free-space optical communication includes a beam splitter, an imaging unit, a specifying unit, a light-receiving unit, and a controller. The beam splitter splits incident light into first and second light beams travelling in different directions. The imaging unit captures an image of the first light beam. The specifying unit extracts a signal light beam from the image of the first light beam and specifies a position of the signal light beam in the image. The light-receiving device receives the second light beam. The controller controls a blocker on the basis of the position of the signal light beam to allow only a limited portion of the second light beam to enter the light-receiving device and prevent a remaining portion of the second light beam from entering the light-receiving device. The limited portion of the second light beam includes the signal light beam.
