Abstract: An optical device is disclosed. An optical device of the present invention that generates a depth map for an object comprises: a projector for irradiating electromagnetic waves onto an object; an optical receiver for receiving reflected waves reflected from the object; and a processor for generating a first depth map for the object on the basis of the direction of arrival of the received reflected waves, generating a second depth map for the object on the basis of the arrival time of the received reflected waves, and combining the first depth map and the second depth map and generating a depth map for the object.
