    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： A 3D printer comprises a scanning laser system. A donor sheet is located in the focal plane of the optical system and carries a thermally transferable colourant such as a dye or pigment. A lenticular screen has a colourant receiving layer which receives colourant from the donor sheet to form 3D pixels, each comprising interlaced 2D pixels, aligned with lenticules of the screen. A detector array responds to laser light which has been transmitted through the lenticular screen, and a print register control system uses the detector output correctly to position the scanning laser beam to compensate for irregularities in the lenticular screen.
