摘要： A hologram reproduction method for reproducing a hologram from an optical recording medium in which the hologram is recorded by Fourier transforming a signal light, in which digital data is represented by an image of intensity distribution, and a reference light, and simultaneously irradiating the lights in a state in which a direct current component is removed from at least the Fourier transformed signal light onto the optical recording medium is provided. The method including: irradiating a read out reference light onto the optical recording medium, and generating a diffracted light from the recorded hologram; generating all or a part of a direct current component contained in a Fourier transformed image of the signal light; combining the diffracted light and the generated all or a part of the direct current component, and generating a combined beam; and reproducing the signal light by inverse-Fourier transforming the combined beam.
