Abstract: A laser beam (L50) generated by a laser light source (50) is reflected by a light beam scanning device (60) and irradiated onto a hologram recording medium (45). On the hologram recording medium (45), an image (35) of a scatter plate is recorded as a hologram by using reference light that converges on a scanning origin (B). The light beam scanning device (60) bends the laser beam (L50) at the scanning origin (3) and irradiates the laser beam onto the hologram recording medium (45). 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 (L60) on the hologram recording medium (45) changes with time. Regardless of an irradiation position of the beam, diffracted light (L45) from the hologram recording medium (45) produces a reproduction image (35) of the scatter is plate on the spatial light modulator (200).
