<P>PROBLEM TO BE SOLVED: To provide a holographic stereogram creation device capable of accurately achieving effects of double refraction of a recording medium in creating a holographic stereogram and capable of being miniaturized. <P>SOLUTION: A holographic stereogram creation device comprises: a reference light generating unit for generating reference light from coherent light emitted from a light source; an object light generating unit for generating object light obtained by modulating the coherent light in accordance with recording information from the coherent light; an exposure optical system for spatially separating optical paths of the reference light and the object light from each other and for crossing the optical paths of the reference light and the object light and making the optical paths interfere with each other; a supporting unit for supplying and supporting a recording medium at a recording position at which the optical paths of the reference light and the object light cross; a polarization state detecting unit for detecting a polarization state of the reference light transmitted through the recording medium; and a polarization state varying unit for changing the polarization state of the reference light in accordance with the polarization state of the reference light. <P>COPYRIGHT: (C)2012,JPO&INPIT |
