Process and method employing dynamic holographic display medium

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. By using a delta image updating in Fourier space, the instant system will speed up image generation significantly; since it is often the case that an object's spatial frequency components change more slowly than its position.
