Abstract

A combination of computer generated hologram (CGH) with a small liquid crystal display, phase-shifting detection, and Twyman-Green interferometer is used to test an aspheric. This method resolves the problem of real-time produce CGH. In the paper, a method of producing real-time computer generated hologram is proposed in which a small liquid crystal display is adopted as a recording material. The making principle of the real-time computer generated hologram is described. The experimental result is better.
