Abstract
A optical transmission device comprising a light source, a spatial light modulator which has a modulation part onto which light emitted from the light source is radiated, and which modulates the phase of the radiated light by means of the modulation part, and a control unit which allocates modulation regions associated with respective communication targets to the modulation part of the spatial light modulator, configures, in each modulation region, a phase image for forming an image used in communication with the communication target in the position of the communication target, and controls the light source such that light is radiated onto the modulation part while the phase image is configured therein.
