The development of a ferroelectric liquid-crystal-over-single-crystal-silicon spatial light modulator is described. The reflective SLM has an array of 176 X 176 pixels over a clear aperture of 5.28 mm X 5.28 mm. Prototype devices driven from a specially designed high speed frame store have been operated at frame rates of approximately equals 1 kHz.

A transmissive, analogue, active backplane electrically addressed SLM using chiral smectic liquid crystals is described with CdSe TFTs to switch the pixels. The device consisted of a matrix of 200 im x 200 im pixels forming 128 rows by 190 columns. The liquid crystal used was 854E (BDH Ltd. England) which allowed observation of the device behaviour in both the smectic C* (ferroelectric switching) and smectic A (electrocinic effect switching) liquid crystal phases. Some observations are made concerning each of these.
