Abstract
The present application discloses a see-through display device a light source configured to emit light, a projection optical system configured to project image light generated from the light; a transmissive hologram including a first surface which the image light enters from the projection optical system; and an interface configured to cause Fresnel reflection of the image light deflected by the hologram. The hologram includes a first interference fringe recorded by object light and reference light which are incident on the first surface by means of two-light flux interference. The image light incident on the first surface is deflected by the first interference fringe toward the interface. The interface reflects the image light toward the first surface.
