Abstract
An optical device includes a planar-image forming unit configured to emit light that forms a planar image of a predetermined shape in a space, and an outline-image forming unit configured to emit light that forms an outline image with a light intensity different from the light intensity of the planar image at the outer-edge region of the planar image.
