Abstract
This communication system includes: at least one transmitter which emits signal light; and a receiving device which receives the signal light. The receiving device is provided with: a control unit which generates a phase image on the basis of position information indicating a position of the transmitter, and combines a virtual lens image with the phase image to generate a composite image; a phase-modulation spatial light modulating element which receives the composite image and diffracts and collects signal light; and a detector which receives the diffracted and collected signal light.
