Hologram sheet and hologram observation sheet using same, and blinding device

A laser beam generated by a laser light source is reflected by a light beam scanning device and irradiated onto a hologram recording medium. On the hologram recording medium, an image of a scatter plate is recorded as a hologram by using reference light that converges on a scanning origin. The light beam scanning device bends the laser beam at the scanning origin and irradiates the laser beam onto the hologram recording medium. At this time, scanning is carried out by changing a bending mode of the laser beam with time so that an irradiation position of the bent laser beam on the hologram recording medium changes with time. Regardless of an irradiation position of the beam, diffracted light from the hologram recording medium produces a reproduction image of the scatter plate on the spatial light modulator. The modulated image of the spatial light modulator is projected onto a screen.

The spatial light modulatorcomposed of a liquid crystal display, etc., is disposed so as to overlap on the position of the hologram reproduction real image, thereby obtaining a modulated image on a surface of the reproduction real imageof the scatter plate. The modulated image is projected onto the screenby the projection optical system. The light bending deviceis composed of a diffraction grating in which the pitch and direction of the grating lines are changed in terms of time, wherein the irradiation angle of the parallel light flux LL is changed in terms of time, and the illumination light beam scans on the screen.
