Abstract

A new high-speed driver has been developed for the magneto-optic spatial light modulator (SLM). The driver allows the output of an image sensing device such as a CCD array to drive the SLM. Using digital circuitry, high frame rates are made possible. Furthermore, the digital nature of the interface allows real-time digital image processing to be performed on input imagery; the input image can be processed by a 3 X 3 kernel. For example, functions such as noise filtering, edge detection, or thresholding can be performed in real-time. Adaptive filters or multiple filter operations on the same data are also possible. Processed imagery can be displayed on the SLM at over 400 frames/second. In addition, the interface can be applied to other electrically-addressed SLMs. The potential for higher frame rates is possible with faster electronic components.
