Abstract
Disclosed herein is a raster scanning-type display device using a diffractive optical modulator. The raster scanning-type display device includes an optical illumination unit, a diffractive optical modulator, and a projection unit. The optical illumination unit radiates light, which is emitted from a light source, in a spot beam form. The diffractive optical modulator causes an element to modulate the spot beam incident from the optical illumination unit, and generate diffracted light whose intensity is adjusted and which has a plurality of diffraction orders. The projection unit generates an image by projecting the diffracted light incident from the diffractive optical modulator onto a screen in a scanning spot beam form and performing raster scanning in which horizontal scanning and vertical scanning are alternated.
