Abstract: The present invention employs a beam dividing prism corresponding to a size of a single pixel on a screen in order to create a plurality of viewing zones for multi-viewer, in which a prism panel having an 1-dimensional or 2-dimensional arrangement of a prism cell for dispersing beam in various directions is coupled to the 3-dimensional image projection screen in order to increase the number of the viewing zones, and in which the number and position of the available viewing zones are determined by the number and a relative position of disperse surfaces in the prism cell. By using the present invention, the desired number of the viewing zones can be created by selectively adopting the prism cells, so realizing the 3-dimensional image display system for multi-viewer.

Abstract: An apparatus for making a high quality reflection type holographic optical element (HOE) using a single input laser beam, including a reflective mirror, a holographic photoplate having a photo emulsion layer on a surface nearest the reflective mirror, a cassette for retaining the reflective mirror and the holographic photoplate, and a refractive index matching fluid containing a light absorbent dye for absorbing an input laser beam. The cassette is immersed in the fluid so that fluid is retained between the photo emulsion layer of the holographic photoplate and a reflective surface of the reflective mirror. Parasitic interference patterns are suppressed by heating the refractive index matching fluid with the input laser beam, which causes a shift of the phase of the parasitic beams with respect to the phase of the beams responsible for recording the HOE. If the photo emulsion layer of the holographic photoplate consists of a dichromated gelatin (DCG), then a photo sensitizer agent (e.g.

Abstract: A multiview three-dimensional image display system comprises an image projection screen, two image generation components, a bifold mirror, an spatial light modulator, and projection optics. Each of the image generation components generates successive finite time sequences of time-multiplexed multiview images and thus form a channel of multiview images. Each of the reflecting surfaces of the bifold mirror reflects a different one of the two channels of multiview images. The spatial light modulator comprises a plurality of strip-like shutters, each of which transmits a different one of the finite time sequences of time-multiplexed multiview images. The projection optics projects the images through the spatial light modulator onto the image projection screen, where the spatial light modulator is imaged to make a single viewing zone.

A diverging or diffusive beam having an angle of divergence greater than the incident angle satisfying the Bragg condition of the holographic optical element under measurement. The apparatus comprises a multi-wavelength oscillation laser beam source, a beam diffuser, a objective lens, and an image projection screen.
