<p>[Problem] To make it possible to selectively receive an arbitrarily defined light beam among light beams from a plurality of light sources in optical communication in free space. [Solution] This light receiving apparatus is provided with at least a beam splitter, a space dividing device, and a light receiver. The space dividing device is composed of an aggregate of mirrors that are arranged in a planar space and each have an arbitrarily changeable reflection angle, and is configured to be able to selectively introduce only an arbitrarily defined light beam from among a plurality of light beams incident on the aggregate into the light receiver by controlling the reflection angles of the mirrors.</p> |
