Abstract
We report what are to our knowledge the first results from a liquid-cr ystal-on-silicon spatial light modulator that uses the distorted helix ferroelectric mode to perform analog Light modulation. The spatial li ght modulator is an electronically addressed analog 128 x 128 pixel de vice with which we have demonstrated 16 gray levels and contrast of 33 :1 in the zeroth diffracted order and 6:1 when imaged. The liquid-crys tal switching speed in this device is approximate to 235 mu s, which w hen added to the data load time of 100 mu s gives a maximum frame rate of approximate to 3 kHz.
