摘要： The invention relates to a holographic viewing device that enables a bright reconstructed pattern to be viewed in place of light sources in a scene while a spot due to zero-order transmitted light is kept unnoticeable, and a computer-generated hologram for the same. The invention provides a holographic viewing device comprising a frame and a computer-generated hologram fitted in the frame. The computer-generated hologram is constructed as a transmission Fourier transform hologram. The computer-generated hologram comprises minuscule cells having pitches δx and δy with a reconstruction image area defined by a range of spreading of ± first-order diffracted light of given wavelength from a diffraction grating having grating pitches 2δx and 2δy that are twice as large as said pitches of cells, and an input image pattern 35 reconstructed at that wavelength is recorded in the computer-generated hologram in such a way that a light portion 36 of the input image pattern overlaps the center of the reconstruction image area.

摘要： A recording plane of a computer-generated hologram that is capable of reconstructing a full-color image and achieving a high resolution is divided by a multiplicity of parallel sections in the horizontal direction to define a multiplicity of areas. Amplitude information and phase information corresponding to different wavelengths which vary periodically in a direction traversing the multiplicity of areas, is recorded in the recording medium. Information about the same portion of the original image is recorded in individual points belonging to the same area, and information about another corresponding portion of the original image is recorded in individual points belonging to another area.

An optical element is arranged by aligning a plurality of three dimensional cells C1(x, y) two dimensionally on an XY plane. Each individual cell is made of a light transmitting material and has a specific amplitude and a specific phase defined therein. The individual cell has a specific optical characteristic such that when predetermined incident light is provided from the upper surface or a lower surface of the cell, transmission emitted light, with which amplitude and phase of the incident light have been changed in accordance with the specific amplitude and the specific phase defined in the cell, is obtained from the lower surface or the upper surface of the cell.
