摘要： It is an object of the present invention to implement a display providing high optical efficiency irrespective of the size of a light valve, and capable of enhancing the uniformity of the luminance of an image to be projected. In order to attain the foregoing object, for example, as shown in FIG. 1, a light valve 103 of a projector is located roughly at the focus point of an illumination lens 102. Further, as shown in FIG. 2, a light source 101 is also located roughly at the focus point of the illumination lens 102. Consequently, it is possible to implement a miniaturized projector.

摘要： A display system has a directional reflection screen with a triangularly-shaped mirror sheet as horizontal focusing for observers and stereoscopic image projecting means. The directional reflection screen has a triangularly-shaped mirror sheet with included angles at least some of which are non-right angles. This enables a plurality of observers to simultaneously obtain a stereoscopic view using a binocular parallax without wearing special glasses and without having to position themselves in a very limited number of positions relative to the screen. Vertical diffusion can also be provided by using a lens sheet. The screen can be made concave in the horizontal or vertical directions, or both.

摘要： High-grade three-dimensional images can be observed without a bright image of an exit end of an image projector superposed on the three-dimensional images. In a method of reproducing three-dimensional images by a three-dimensional image-reproducing device provided with an image projector and a directional reflective screen for collecting light from the image projector toward a specific position in a horizontal direction and for diffusing the light in a vertical direction, the directional reflective screen and the image projector are positioned with respect to the observer observing the three-dimensional images such that the observer is outside a region traversed by a portion of light rays which enter the directional reflective screen from the image projector, then are reflected by a surface of the directional reflective screen incapable of contributing to the reproduction of the three-dimensional images, and form a mirror image or a conjugate image of the image projector.

摘要： An objective lens converges a shorter wavelength laser beam on a DVD having a protective layer, which is 0.6 mm thick, and a longer wavelength laser beam on a CD having a protective layer, which is 1.2 mm thick. A common region is defined on the objective lens. The common region provides a numerical aperture appropriate for converging the longer wavelength laser beam on the CD. Coma of the objective lens in the first region is compensated better in a case where the longer wavelength laser beam is converged on the CD than a case where the shorter wavelength laser beam is converged on the DVD.

摘要： In a laser printer wherein a photoconductive drum is scanned by utilizing a plurality of laser beams, there are detected spacings between the plural laser beams, such detection being confined to a blanking time. On the basis of the detected results, the spacings between the plural laser beams are controlled; and this state is maintained for a printing time. With this arrangement, it is possible to accurately detect the spacings between the plural laser beams thereby to obtain the practicable laser printer employing the plural laser beams.
