    Abstract: PROBLEM TO BE SOLVED: To provide an optical information reproducing device capable of reproducing an interference pattern recorded by using information light generated by spatially modulating phases of light. SOLUTION: A hologram producing device is disclosed, which includes: an object light generating means 102 generating object light in a first polarization direction; a reference light generating means 103 generating reference light in a second polarization direction orthogonal to the first polarization direction; an irradiating means 104 irradiating a hologram recording layer 112 of a recording medium 111 through the top face with the object light and the reference light; a polarized light selective reflection means 106, disposed in the backside of the hologram recording layer, reflecting only one of the object light and the reference light transmitted through the hologram recording layer toward the hologram recording layer; and a polarization converting means 105 disposed between the hologram recording layer and the polarized light selective reflection means, converting the polarization direction of the reflected one of the object light and the reference light into a polarization direction orthogonal to the original direction. A reflective hologram 115, which is formed in the hologram recording layer by the interference between the one of the object light and the reference light with the other of the object light and the reference light incident to the top face of the recording medium, is recorded in the hologram recording layer.

    Abstract: PROBLEM TO BE SOLVED: To provide a computer generated hologram which forms a light intensity distribution (reproduced image) in a desired form and polarizing state while controlling uneven illuminance and light quantity losses. SOLUTION: This computer generated hologram which forms a light intensity distribution on a predetermined plane by giving a phase distribution to a wavefront of incident light, comprises: an anisotropic layer whose refractive index with respect to linearly polarized light in a first direction is different from a refractive index of the anisotropic layer with respect to linearly polarized light in a second direction perpendicular to the linearly polarized light in the first direction; and an isotropic layer whose refractive index with respect to the linearly polarized light in the first direction is equal to a refractive index of the isotropic layer with respect to the linearly polarized light in the second direction. By giving different phase distributions to the wavefront of the linearly polarized light components in the first direction of the incident light, and the wavefront of the linearly polarized light components in the second direction of the incident light, the first light intensity distribution whose linearly polarized light components in the first direction of the incident light form on the predetermined plane is made different from the second light intensity distribution whose linearly polarized light components in the second direction of the incident light form on the predetermined plane.
