    摘要： A polymer dispersed liquid crystal optical device is presented which has optical elements which control reflection, transmission and diffraction of incident light entering the device by adjusting the magnitude of the electrical field applied to the device between a maximum and a minimum limits. An optical element consists of a polymer material having an electrical field-independent refractive index, and a liquid crystal material having an electrical field-dependent refractive index. The optical elements are distributed through the device at specific inter-element spacings, thus enabling to generate reflection of incident light in accordance with Bragg's law of reflection. The inter-element spacings can also be varied by the application of the field, thus enabling to generate reflection of light of a desired wavelength. Such optical elements are ideal for use in full color optical display apparatus of a matrix driven type. Methods for producing the optical device and optical display apparatus are also presented.

    摘要： An original image is divided into a plurality of image parts in the forms of image signals which are then given to liquid crystal light valves, respectively so that liquid crystal light valves display the plurality of image parts therein. These liquid crystal light valves allow light from light sources to pass through so as to form image light beams which are intensity-modulated in accordance with the divided image parts. A plurality of mirrors reflect the image light beams and introduce them onto a projecting lens system. In this arrangement, the plurality of mirrors are located in such a way that their reflecting surfaces do not cross the optical axis of the projecting lens system, and the image light beams are synthesized on the screen so as to reproduce an original image. Accordingly, the pixel density of the original image can be multiplied by a multiplier which equal to the number of used liquid crystal light valves.

    摘要： A videocamera is disposed diagonally to the front of a display and the image of a subject is reflected toward the videocamera by a half-transparent mirror placed in front of the screen of the display. The half-transparent mirror has in its front inclined strip-like micro reflective surfaces and inclined strip-like micro transparent surfaces which emit therethrough incident light from the display screen. The angle between each micro transparent surface and a strip-like micro area formed on the back of the half-transparent mirror in opposing relation to the micro transparent surface is determined so that the half-transparent mirror has a light collecting or condensing effect.
