摘要： A volume-phase reflection hologram optical element is fabricated by exposing a hologram photosensitive material to two coherent light beams. One exposure light beam has an axis-asymmetric wavefront, and the other exposure light beam has focus points different in the optical axis direction (Z-direction) between on a plane (ZX-plane) including one of two directions (X- and Y-directions) mutually perpendicular on a sectional plane perpendicular to that light beam and on a plane (YZ-plane) including the other of those two directions. Thus, an image display apparatus is realized in which at the time of reproduction, the component of a predetermined wavelength of the image light diffraction-reflected by the hologram optical element is focused at positions different in the optical axis direction between on the ZX-plane and on the YZ-plane, offering different image viewing characteristics between in the X- and Y-directions.

摘要： As a result of the light from a plurality of point light sources located at an identical position being refracted at a surface of a color correction prism at the time of exposure, the chromatic aberration occurring as a result of the light (for example, image light) directed via a refractive surface of the optical system used at the time of reconstruction to the viewer's pupil being refracted at this refractive surface is corrected for. Moreover, at least two of another set of a plurality of point light sources are arranged at such positions as to provide angles of incidence commensurate with the deviation between them of the ratio between exposure wavelength and use wavelength. Thus, even in a case where the ratio between exposure wavelength and use wavelength differs between at least two colors, it is possible to make equal for all colors the angle of diffraction that provides the maximum diffraction efficiency at the hologram optical element at the time of reconstruction, and thereby to correct for color shifting depending on the viewing angle.
摘要翻译：由于来自位于相同位置处的多个点光源的光在曝光时在色彩校正棱镜的表面处被折射的结果是由于光而产生的色像差（例如，图像光）经由重建时使用的光学系统的折射表面被引导到在该折射表面处被折射的观察者的瞳孔。此外，另外一组多个点光源中的至少两个设置在这样的位置处，以提供与曝光波长和使用波长之间的比率之间的偏差相对应的入射角。因此，即使在曝光波长和使用波长之间的比例至少两种颜色之间不同的情况下，也可以使全息图光学元件的衍射效率在全息光学元件时提供最大衍射效率的所有颜色相等重建，从而根据视角校正颜色偏移。

摘要： A first HOE and a second HOE are respectively arranged on two opposite faces of an optical waveguide member. The first HOE diffracts light incident from the outside on the optical waveguide member such that the light is then totally reflected inside the optical waveguide member and is thereby directed to the second HOE. The second HOE diffracts, according to the diffraction efficiency thereof, part of the light incident thereon after being guided inside the optical waveguide member such that this part of the light is then emitted to the outside substantially parallel to the light incident on the optical waveguide member, and the second HOE simultaneously totally reflects the rest of the light incident thereon. The second HOE repeats such emission and total reflection. The first and second HOEs each have interference fringes with n different pitches (where n is a natural number equal to or greater than two) to diffract light of n different wavelengths at substantially equal angles. Thus, even when light of n different wavelengths is incident on the optical waveguide member, the second holographic diffractive optical element emits it to the outside with substantially equal pitches for the light of the n different wavelengths.
摘要翻译：第一HOE和第二HOE分别布置在光波导构件的两个相对的面上。第一HOE将从外部入射的光衍射到光波导构件上，使得光在光波导构件内部全反射，从而被引导到第二HOE。第二HOE根据其衍射效率衍射在光波导部件内被引导之后入射到其上的光的一部分，使得该部分的光然后被发射到基本上平行于入射在光波导部件上的光的外部并且第二HOE同时完全反映入射到其上的光的其余部分。第二个HOE重复这种排放和全面反射。第一和第二HOE各自具有n个不同间距（其中n是等于或大于2的自然数）的干涉条纹，以基本相等的角度衍射n个不同波长的光。因此，即使在n个不同波长的光入射到光波导部件上的情况下，第二全息衍射光学元件对于n个不同波长的光以相等的间距发射到外部。

摘要： Information light modulated and emitted by a modulation element is led to a recording medium through a Fourier transform optical system and an optical path shifter. An interference image is recorded on the recording medium by interference of the information light and reference light. A deflection unit of the optical path shifter has a pair of prisms. Optical path of information light transmitted through the respective prisms are shifted in parallel in a direction perpendicular to an optical axis of the Fourier transform optical system. By rotating the deflection unit around the optical axis, it is possible to shift the optical path of the information light around the optical axis while shifting the optical path in the direction perpendicular to the optical axis. Therefore, it is unnecessary to perform complicated control and it is possible to multiply record an interference image accurately with an information recording apparatus having a simple structure.
