Paper Abstract

In order to implement computer generated holograms (CGHs) and correlation plane filters (CPFs) on an LCTV SLM, the pixel-level complex-amplitude properties of the modulator must be accurately known. These properties must then be incorporated into algorithms for achieving the pixel-level control via a frame grabber (FG) and NTSC video signal. Within this investigation we present techniques for measuring the properties of FG-to-video-to-LCTV system, and then develop an algorithm to allow pixel-level control of the LCTV.
