摘要： There is provided an optical device including an optical waveguide upon which a group of parallel light beams different in traveling direction from each other are incident and from which the group of parallel light beams go out after propagated by repeated total reflection through it. The optical waveguide includes a first reflection-type volume hologram grating, and a second reflection-type volume hologram grating. The pitches of interference fringes on the hologram surfaces of the first and second reflection-type volume hologram gratings are equal to each other. In at least the second reflection-type volume hologram grating, the angle formed between the interference fringes and hologram surfaces are varied continuously or stepwise within the hologram in relation to the main incident light beam so as to meet the Bragg condition. Therefore, it is possible to reduce the unevenness of color and brightness due to angles of view.

摘要： The present invention relates to an image display device in which a virtual image of an image display element is formed to display an image. The image display device includes a transmission type diffraction optical element (50) for diffracting exit lights from the image display element (20) and a reflection type optical element (70) having a positive optical power for reflecting the diffracted lights from the transmission type diffraction optical element (50). When the reflected lights reflected by the reflection type optical element (70) are incident again on the transmission type diffraction optical element (50), the transmission type diffraction optical element (50) diffracts the reflected lights with a diffraction efficiency lower than a diffraction efficiency for the exit lights from the image display element (20).

摘要： The present invention relates to an image display device that is suitably applicable to, for example, a projector using an ultrahigh-pressure mercury lamp as a light source. In a light source of the present invention, main light is partially replaced with auxiliary light in a wavelength region in which the intensity of the main light is less than that of the auxiliary light. That is, the light source includes an illumination-light combining member that generates illumination light by strengthening the wavelength region of the emission spectrum of the main light with the auxiliary light. Accordingly, the loss of main light is satisfactorily reduced, and the light intensity in the wavelength region in which the intensity of the main light is insufficient is compensated for. Further, light emitted from the main light source formed of a lamp or the like is efficiently utilized, and a bright image can thereby be displayed with high color reproducibility.

摘要： A disc table employed in a disc recording/reproducing apparatus has, as a recording medium, a recording disc, such as an optical disc or a magneto-optical disc, on which information signals are pre-recorded or are to be recorded. The disc table includes a fitting member fitted from its distal end into a circular center aperture of the recording disc, a table section which is integrated to the fitting member at a proximal side of the fitting member and on which a rim portion around the center aperture of the disc is set, a thrusting and supporting unit for thrusting and supporting the recording disc with respect to the table section, and a centering unit provided at a proximal side of the fitting member and adapted for thrusting the rim portion around the center aperture of the recording disc for aligning the center of rotation of the recording disc with the center of rotation of the fitting member. The fitting member is gradually tapered towards its distal end where the fitting member is provided with a guide slidingly contacted with the inner rim of the center aperture of the recording disc for guiding the recording disc towards the center of rotation of the fitting member. The recording disc may be positively centered to enable stable rotation of the recording disc while realizing a simplified thin type construction.
