<p>[Object]Provided are a hologram generating device and a hologram generating method that allows the generation of a hologram for reproducing an easily observable three-dimensional image without restrictions on object sizes. [Solving means] The hologram generating device includes an object light generation means 102 for generating object light 12) in a first polarization direction, a reference light generation means 103 for generating reference light 122 in a second polarization direction intersecting with the first polarization direction at right angle, an irradiation means 104 for irradiating with the object light and the reference light from the front surface side, a polarization light selecting reflection means 106 placed on the rear surface side for reflecting only either one of the object light and the reference light transmitting through a hologram recording layer, and a polarization conversion means 105 placed between the hologram recording layer and the polarization selecting reflection means for converting the polarization direction of one of the reflected object light and reference light to a polarization direction intersecting with that of the reflected one at right angle, wherein the one of the object light and the reference light incident from the rear surface is made to interfere with the other of the object light and reference light incident from the front surface in the hologram recording layer to record a reflection type hologram 115 on the hologram recording layer.</p> |
