摘要： In recording of information, an information beam as S-polarization is incident on an optical information recording medium. After passing through the optical information recording medium, the information beam is reflected by reflection apparatus and passes through a polarization controller. In this process, the information beam undergoes S-polarization control and the polarization direction changes to P-polarization direction. The information beam interferes with a recording reference beam as P-polarization incident on a surface of the optical information recording medium inside the optical information recording medium to form an interference pattern. In reproduction of information, a reproduction reference beam is incident on the surface of the optical information recording medium. The reproduction reference beam is then diffracted by a refractive index grating caused by an interference pattern formed in the optical information recording medium to form a reproduction beam. The reproduction beam is emitted from the surface of the optical information recording medium and is incident on a light receiving element. The original data is then reproduced.

摘要： A holographic recording and reproduction apparatus has a spatial light modulator for converting digital information to a two-dimensional image and for intensity modulating an object beam based on the two-dimensional image. The spatial light modulator is configured to employ four or more pixels on the two-dimensional image as a unit pixel block, and allow at least two types of encoded patterns having a different number of ON pixels in the unit pixel block to be present at the same time for display of the two-dimensional image. During a reproduction operation, a two-dimensional photodetector detects the amount of light on per unit pixel block basis to determine the number of its ON pixels and then set a threshold, and thereafter an image pickup device detects the image.
