摘要： A holographic optical information recording/reproducing device is provided with a laser light source 1 and a polarizing beam splitter 8 for splitting a light from the laser light source 1. At the time of recording information, one of light beams split by the polarizing beam splitter 8 is modulated by a spatial light modulating element 2 to form a beam array, which becomes a signal light 25, whereas the other split light beam becomes a reference light 22. Interference fringes generated by the signal light 25 and the reference light 22 are recorded as holograms in a holographic disc 5. At the time of reproducing the information, only the reference light 22 is irradiated to the holographic disc 5 and its diffracted light is detected. At this time, the holographic optical information recording/reproducing device makes the power of the reference light 22 in the holographic disc 5 for information reproduction larger than a sum of the power of the reference light 22 and the power of the signal light 25 in the holographic disc 5 for information recording.

摘要： Disclosed is an arrangement that enables to keep a relative positional relation between a beam for servo control and a beam for information recording/reproduction constant concerning focusing control and tracking control, even if the two beams are different from each other. An optical storage medium has a reflection surface for reflecting a first beam having a first wavelength, and reflecting a second beam having a second wavelength different from the first wavelength; and an information storage layer for recording information as an interference pattern by incidence of the first beam, or reproducing the information from a wave surface based on the interference pattern. The reflection surface is formed with plural marks or guide grooves usable in a tracking operation or a focusing operation by irradiation of the second beam. The information storage layer is partially formed, in advance, with a reference interference pattern which is reproduced when the first beam is irradiated, and which is used as a reference for correcting the relative positional relation between the first beam and the second beam.

摘要： A two-dimensional image formation device of the present invention is provided with a spatial light modulation element (7) for modulating light having a linear polarization and emitted from a laser light source (1), and a depolarization means (21) for depolarizing the modulated light before it is incident on an image display surface. The light having a linear polarization is used before and after incidence of irradiated light to the spatial light modulation element (7), and the linear polarization of the irradiated light is depolarized after the modulation, whereby randomly polarized light is projected on a screen (11). Thereby, speckle noise is significantly reduced, and a high-definition image can be formed.
