摘要： Arrangements are made to enable different original images to be reproduced upon observation from different positions and yet enable reproduced images of high resolution to be obtained. Each of two original images Ia and Ib is defined as a set of point light sources such as P11 and P21 in an XYZ coordinate system. A predetermined recording plane 20, a reference light R, and two observation regions Oa and Ob are set in the coordinate system. An interference fringe pattern, formed on the recording plane by object light components La1 to Lb2, from the point light sources constituting the respective original images, and the reference light R, is determined by computation and is recorded on a physical medium. In this process, in regard to the object light components from the point light source P11 belonging to the original image Ia, a computation that takes into account only the light components that reach the observation region Oa is performed, and in regard to the object light components from the point light source P21 belonging to the original image Ib, a computation that takes into account only the light components that reach the observation region Ob is performed. The original image Ia is reproduced upon observation from the observation region Oa and the original image Ib is reproduced upon observation from the observation region Ob.

摘要： A complex amplitude type spatial optical modulation element, with which the amount of generation of 0th-order diffraction light is low, is provided. An optical element is arranged by aligning a plurality of three-dimensional cells C1(x, y) two-dimensionally on an XY plane.

On the upper surface of each individual cell, a first region, in which a groove G(x, y) is formed, and a second region, positioned at both sides of the first region, are formed, and light blocking layers F1 and F2 are formed on upper surfaces of the second region. The first region, which is a bottom surface of groove G(x, y) is set to an area (G1×G3) that is in accordance with the specific amplitude defined in the corresponding cell, and the depth (G2) of groove G(x, y) is set to a value that is in accordance with the specific phase defined in the corresponding cell. Incident light from the upper surface of a cell is modulated by the specific amplitude and the specific phase in being transmitted to the lower side of the cell.

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.
