    • There is provided an optical reproduction device that reproduces a hologram that is recorded on an optical recording medium by interference between a signal light and a reference light coaxial to the signal light. The device has: a coherent light source; a light distribution unit distributing light from the light source, to a signal light optical path and a reference light optical path; a spatial light modulator that includes a signal light region and a reference light region, a spatial light modulator, a first irradiation optical system spatially separating light distributed to the reference light optical path and light distributed to the signal light optical path, making optical axes of both lights coincide, and irradiating the both lights onto the spatial light modulator; and a second irradiation optical system irradiating reference light onto the optical recording medium as reading light, and reproducing the hologram.
