ABSTRACT:
There is provided an optical reproducing device including: a reproducing component that includes a light source, a spatial light modulator, and a light guiding component, with the reproducing component irradiating, with reference light that has been generated by the spatial light modulator as reading light, a Fourier transform hologram; a splitting component disposed on a signal light exiting side of the reproducing component and that splits, into two light waves, the signal light; a first image acquiring component that detects the one split light wave to acquire a first reproduced image; a second image acquiring component that detects light where a direct current component has been removed from the other split light wave to acquire a second reproduced image; and a decoding component that uses the first reproduced image and the second reproduced image to decode data that the signal light has.
