摘要： An integrated three-dimensional display includes a recording surface which includes a calculated element region in which phase components of light from light converging points of a holographic reconstructed image are calculated, and a phase angle recorded area for recording a phase angle calculated based on the phase components. The phase angle recorded area includes a plurality of monochromatic regions having a uneven structure surface. The phase angle is recorded in an overlap area in which the calculated element region and the phase angle recorded area overlap each other. Light converges on the light converging points at specific distances from the recording surface, the specific distances being determined for the respective light converging points even when light reflected from the plurality of monochromatic regions converges.

摘要： A hologram recorder is provided, in which coherent light from a light source is split into a signal beam and a reference beam, and the signal beam is modulated by a spatial light modulator to be directed to a hologram recording medium, while the reference beam is directed to the hologram recording medium to overlap with the signal beam for recording a hologram on the hologram recording medium. The hologram recorder includes a beam phase modulator provided with a plurality of optical devices (20p, 20p′) each configured to assume one of two modes such as ON mode and OFF mode, the ON mode for causing the reference beam to be passed or reflected in a predetermined direction toward the hologram recording medium, the OFF mode for causing the reference beam to be blocked or directed in another direction other than the predetermined direction. Each optical device (20p, 20p′) provides a phase difference 0 or π. A phase modulation controller is also provided for individually controlling the optical devices (20p, 20p′) to cause each of the optical devices to assume the ON mode or the OFF mode, thereby modulating the reference beam into a beam having a predetermined phase pattern.

摘要： A uniform-brightness, high-gain projection screen is especially suited for reflecting radiation from a projector to a viewer who is spaced from the projector along a projection axis. The screen is formed with a plurality of reflective faces that each form at least a portion of a ring that is transverse to the projector axis, have different spacings from the projector and are axially tilted to set the projector-face angle equal to the viewer-face angle. The faces are preferably defined by a plurality of tiles that are bonded to the interior of a projection dome such as a flight simulator dome.

摘要： A recording technique for performing data recording onto a hologram recording medium in accordance with information on phases by performing spatial light phase modulation as spatial light modulation corresponding to recording data, and a reproducing technique for reproducing recorded data by properly reading information on phases recorded as described above are suggested. A signal beam having a phase modulation pattern provided thereto corresponding to recording data and a reference beam having a specific phase modulation pattern provided thereto are applied to the hologram recording medium. Thus, recording data can be recorded onto the hologram recording medium in accordance with information on phases. In addition, at the time of reproduction, a reference beam and a DC beam having the entire phase whose phase difference with respect to a reference phase within the reference beam is π/2 are applied to the hologram recording medium. By providing a phase difference based on π/2 as described above, the phase of a reproduction beam obtained from the hologram recording medium in accordance with application of the reference beam and the phase of the DC beam can be set to be the same. Thus, the DC beam can be added as a component of an amplitude of “1” to the reproduction beam. By reading the reproduction beam to which the DC beam is added as described above, recorded information on phases can be correctly read, and recorded data can be reproduced in accordance with the phase information.
