SPATIALIGHT™

SLM M4-704X512 Spatial Light Modulator

DK-4 Drive Electronics Module

General Description

The SLM M4-704X512 is a nematic active matrix liquid crystal spatial light modulator. The SLM functions as an electrically variable retarder, offering as many as 256 levels per pixel. The matrix is arranged as a 2 dimensional array of 704 by 512 pixels on 20mm centers. The reflective SLM can be conveniently integrated into solid or air spaced systems.

The drive electronics module includes software for an IBM compatible PC to download patterns or images. The data format is raw serial data from a binary file, or a Windows 3.1 BMP format file. The data is transferred through the parallel port by a supplied cable, or through the PC bus (ISA) for higher speed operation. An optional Sun/EDT interface is available, or a proprietary parallel interface for very high speed operation.
