FAST SWITCHING OF STLM VALVES OPERATING ON THE BASIS OF TWISTEFFECT IN LIQUID-CRYSTALS

Prototypes of matrix multichannel spatial-temporal light modulators (S TLM) based on liquid crystals (LC) developed so far do not match the o perating capacity of optical computing systems by their characteristic s (response speed, capacity), One of the ways to increase the speed of response of STLM is to realise the modulation mode that arises under deformation of near-electrode LC layers. This paper presents the resul ts of investigation of the modulation characteristics of the STLM ligh t valves based on twist-effect under conditions of initial distortion of LC-layer director that is caused by contact of the liquid crystal w ith the periodic structure of the modulator electrodes.
