<P>PROBLEM TO BE SOLVED: To provide a hologram information regenerative apparatus for achieving miniaturization of the whole apparatus. <P>SOLUTION: The hologram information regenerative apparatus regenerates transmission hologram information formed on an information recording area R of a recording medium 100. The hologram information regenerative apparatus arranges a light source 10A for emitting reference light B on the information recording area R, arranges an optical head having a photodetector 30 for detecting diffracted light obtained when irradiating the reference light B on an interference fringe on one side of the recording medium 100, and arranges a reflection mirror 40 for reflecting and irradiating the reference light B irradiated on the information recording area R of the recording medium 100 as conjugate light on the information recording area R on the other side of the recording medium 100. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
