We demonstrate fast, efficient beam steering using a single 1 x 32 analog ferroelectric liquid crystal (FLC) spatial light modulator. A high-tilt FLC material with 82 degrees 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 0-2 pi phase modulation. Electronic drive based on applied charge gives 200,us response-time analog modulation. (C) 2009 Optical Society of America
