  • Patent number: 6405567
    Abstract: A reduced dispersion optical waveguide and methods of fabricating the same are implemented. The optical waveguide may be fabricated in commercially practicable units without having to predetermine its length in a particular application. The reduced dispersion optical waveguide prevents optical pulse overlap in optical waveguide transmission systems operating over long distances or at high data rates.
    Type: Grant

  • Patent number: 6178018
    Abstract: Conventional display technology can be used to display crude computer generated holograms (CGH), and can be extended to moving displays. However, the ones best suited from the standpoint of illumination flexibility, such as the common Liquid Crystal Displays (LCDs), switch very slowly. Thus systems with far better dynamic—rapid response requires very complex drive electronics. A non-memory ceramic PLZT, dynamic holographic display medium, provides much faster response time relative to common LCD technology. This system, which is the major embodiment of the present invention, also exhibits good spatial display capability. The system of the present invention, can display Fast Fourier Transformation (FFT) Computer Generated Holograms (CHHs); thus allowing the use of FFT based manipulation of images.
