Abstract

We demonstrate fast, efficient beam steering using a single 1×32 analog ferroelectric liquid crystal (FLC) spatial light modulator. A high-tilt FLC material with 82° optic-axis switching provides, in a reflective-mode device with a passive quarter-wave retarder between a half-wave FLC layer and a mirror, 91% of full 02π phase modulation. Electronic drive based on applied charge gives 200μs response-time analog modulation.
