Paper Abstract

A novel SLM based on a two dimensional array of Kerr cell shutters, the electrodes of which have been deposited on PLZT, has been proposed and initial measurements on such devices have been made. The cell or pixel density is 1000 per inch by 500 per inch and operating voltage for 30 light transmission is less than 50 volts. Extension of 1250 X 1250 per inch is the next step. The Kerr cells may be either photo-activated or may be electronically addressed. Pixel to pixel contrast ratios in excess of 750 to 1 have been measured, which implies that the device could have applications as an optical computer element.
