Abstract:
A holographic stereogram exposure apparatus for exposing three-dimensional image information on a hologram recording medium to produce a holographic stereogram, said apparatus comprising:spatial light modulation section having a plurality of portions in a parallax direction, a portion of said plurality of portions displaying an image of a plurality of adjacent images, each of said plurality of adjacent images corresponding to a respective element hologram; an overlay projection optical system receiving a light beam that has passed through said plurality of portions and superposing said plurality of adjacent images displayed on said spatial light modulation section to form a superposed image of said plurality of adjacent images; and a beam-condensing projection optical system condensing said superposed image in said parallax direction and separating said plurality of adjacent images from said condensed superposed image in said parallax direction, said plurality of adjacent images being separated from said condensed superposed image for recording onto said hologram recording medium, a separated image of said separated plurality of adjacent images being recorded onto said hologram recording medium adjacent in said parallax direction to another separated image of said separated plurality of adjacent images.
