Original Abstract Submitted
Provided is a transmission device that includes a light source that includes emitters, a spatial light modulator that includes a modulation part in which modulation regions are set, a concentrator that converts modulated light modulated in the modulation regions into parallel light, a projector that is disposed at a subsequent stage of the concentrator and includes at least one reflector including a curved mirror having a reflection surface of a curved shape having a curvature according to a projection angle of projection light transmitted as a spatial light signal and a rotator rotatably supporting the curved mirror, and a controller that controls the rotator to adjust a reflection direction of the curved mirror for each of the reflectors, sets a phase image used for spatial light communication in the modulation regions, and controls the plurality of emitters such that each of the modulation regions is irradiated with light.
