    摘要： A 3D projection display comprises an autostereoscopic image producing unit which directs light beams corresponding to respective 2D views in different directions towards a projection lens. The projection lens co-operates with the image producing unit to image the light beams at respective different regions in the aperture of the projection lens. A light-transmissive screen co-operates with the image producing unit and the projection lens to image the views at the screen. The screen may comprise a Fresnel lens, or where a magnified image of increased angular spread is required, a double lenticular screen angular amplifier.

    摘要： A three dimensional display is provided which can. operate in an autostereoscopic mode, requiring no viewing aid, and a stereoscopic mode, requiring a viewing aid such as polarized spectacles. In the autostereosocopic mode, light from illuminators is imaged by lenses through LCD display panels at regions where the left and right eyes of an observer are located. Thus, a two dimensional image displayed on one panel is visible to the right eye of the observer whereas a two dimensional image displayed by the other panel to visible to the left eye of the observer. In the stereoscopic mode, light from the illuminators through the LCD panels is visible throughout an extended region by both eyes of the observer. However, the light from the panels is polarized in mutually perpendicular directions and the spectacles comprise polarizers for the left and right eyes which substantially pass only light corresponding to the left and right images, respectively.

    摘要： Disclosed herein is an apparatus for maintaining and converting a localized polarization shift into a localized intensity variation in a liquid crystal display assembly. The assembly includes a liquid crystal display having a back side and a front side, a polarization-maintaining, light-diffusing layer adjacent to the front side of the liquid crystal display, and a front light-polarizing layer disposed adjacent to the polarization-maintaining, light-diffusing layer. A method for maintaining and converting a localized polarization shift into a localized intensity variation in a liquid crystal display assembly also is disclosed.

    摘要： Lithography processes that use multiple layers require registration between layers. The accuracy requirement depends on the application of the lithograph. For microlithography, the registration requirement could be less than one micron. Systems that use lenses for imaging such as optical steppers can image conventional alignment marks through those lenses. A unique microlithography system that employs holograms has properties that are not compatible with known alignment techniques. The present invention is a new system for alignment of holographic microlithography elements.
