Abstract

Electrical address circuits developed for driving fast-switching ferroelectric liquid-crystal spatial light modulators (SLM) can be programmed to increase the speed of much slower responding nematic liquid-crystal SLMs. Using an addressing circuit that can switch as fast as 0.164   ms , voltages are programmed for values of phase that exceed the desired phase, and when the phase reaches the desired value, the voltage is switched to the required steady-state voltage. For a SLM that has a phase range of 3.5 π and that is programmed over a 2 π range, switching speed is reduced from 400   ms to between 71 and 77  ms . The speedup algorithm is applied to each pixel of the SLM together with a digital correction for a spatially nonuniform phase.
