    摘要： A method is described for recording a volume reflection holographic image that is viewable when illuminated by light at a wavelength Wv. The method includes providing a transparent holographic recording medium having a refractive index n, said holographic recording medium being photosensitive to external light provided at a wavelength W that is different than Wv; disposing a first transparent refracting medium in contact with a first surface of the holographic recording medium; and exposing the holographic recording medium to a signal coherent light source that includes image or other information to be recorded in the holographic recording medium and a reference coherent light source, the signal coherent light source and reference coherent light source emitting light at the wavelength W and entering the holographic recording medium through opposing surfaces thereof, wherein the signal coherent light source or the reference coherent light source passes through the first transparent refracting medium before entering the holographic recording medium at an internal angle of incidence greater than arcsin(1/n).

    摘要： The invention provides a method and an apparatus for preparing a digital hologram representing an object (9), comprising generating a measurement beam (11) and two reference beams (10,12), irradiating the object (9) by the measurement beam and guiding the reflected measurement beam to an optical sensor (7), guiding the reference beams to mirror means (5) extending under a slanting angle and guiding the reflected beams to the sensor (7) to make the beams generate an interference pattern on the sensor, providing a digital signal representing the pattern on the sensor, processing the signal to obtain a digital hologram, subjecting the digital hologram to a Fourier transform in the spatial frequency domain to obtain a spectrum comprising a DC-term,
    two image terms (R 1 *O,R 2 *O), and two conjugate image terms (R 1 O*,R 2 O*), filtering the spectrum to obtain a term representing the object and replacing a section of an image term overlapped by the DC-term by the corresponding section of the other image term.

    摘要： In an optical information recording device and optical information recording method for angularly multiplexing and recording data on pages on the same recording region on a hologram disk, data on each page is sequentially generated by sequentially dividing input data in predetermined units, the pages to be recorded on the same recording region are divided into page groups so that pages to be recorded adjacently by the angular multiplexing may not belong to the same group, each page group is individually subjected to inter-page coding processing for computing an error-correcting code and adding the computed error-correcting code, and data on the pages subjected to the inter-page coding processing is angularly multiplexed and recorded on the hologram disk.
