    摘要： A hologram recording/reproducing apparatus includes: a coherent light source; a spatial light modulator which spatially modulates light from the coherent light source; a Fourier transform lens which concentrates light modulated by the spatial light modulator upon a hologram medium; and a two-dimensional light-receiving element array which receives light from the hologram medium. The spatial light modulator is divided into a reference light area and a signal light area, and the divergence angle of reference light emitted from the reference light area is wider than the divergence angle of signal light emitted from the signal light area.

    摘要： A linearly polarized light beam emitted from a coherent light source reaches a polarizing phase plate and is thereby divided into a primary beam and a subsidiary beam having a polarized light component perpendicular to the polarized light component of the primary beam and a double-humped pattern, in which the center position coincides with the center position of the primary beam and the principal portion is equal in size to the principal portion of the primary beam. The primary beam and the subsidiary beam are focused onto an information storage surface of an optical disk and reflected therefrom, so that they are separated again through polarization separation and individually detected by first to third optical detectors. The output signals from the first to third optical detectors are calculated by a differential calculator and outputted therefrom.

    摘要： A transmissive display apparatus includes a transparent display panel, a display unit which projects a display light toward a display area of the transparent display panel, a ratio change unit which is provided to the display area, is configured to be capable of changing a light transmittance, and is configured to be capable of changing a ratio of a light quantity of a rear face reflected light reaching a viewpoint relative to a light quantity of a front face reflected light reaching the viewpoint, and a control unit which alternately switches the ratio change unit between a first state and a second state. The ratio change unit lowers, in the first state, the ratio by reducing the light quantity of the rear face reflected light that reaches the viewpoint in comparison to the second state. The light transmittance increases in the second state in comparison to the first state.

    摘要： A 2-dimensional beam scan unit reflects emission beams from a red laser light source, a green laser light source and a blue laser light source and scans in a 2-dimensional direction. Diffusion plates diffuse the respective light beams scanned in the 2-dimensional direction to introduce them to corresponding spatial light modulation elements. The respective spatial light modulation elements modulate the respective lights in accordance with video signals of the respective colors. A dichroic prism multiplexes the lights of the three colors after the modulation and introduces the multiplexed lights to a projection lens so that a color image is displayed on a screen. Since the 2-dimensional light emitted from the beam scan unit is diffused to illuminate the spatial light modulation element, it is possible to change the optical axis of the beam emerging from the light diffusion member for irradiating the spatial light modulation element moment by moment, thereby effectively suppressing speckle noise.
