  • Holographic projection screen for displaying a three-dimensional color images and optical display system using the holographic screen
    Publication number: 20010006426
    Abstract: A method is proposed, how to produce a holographic screen for projection of the three-dimensional color images, where a narrow and elongate slit-shaped diffuser is recorded on a hologram as an object to ensure the well defined viewing zone forming in the course of the image projection. Further to the back side of the holographic screen a mirror is attached to transform it into reflection mode of operation. Further, the holographic screen is rotated under a control of an eye-tracking system to provide viewing zone movement together with a viewer's eye. Also, a diffuser with vertical light scattering is attached to a surface of the holographic screen to increase a vertical size of a viewing zone of the holographic screen. In addition, two or more holographic screens manufactured by this method are combined in a mosaic manner to form a big size holographic screen.
