Large-angle beam steering using all-optical liquid crystal spatial light modulators

We have demonstrated operation of an all-optical liquid crystal (spatial light modulator) used for steering a laser beam over large angles. Continuous steering over ±12.4° is achieved, controlled by the power of an infrared pump beam; This is a very large steering angle for a nonmechanical nondiffra...

Description
Summary:We have demonstrated operation of an all-optical liquid crystal (spatial light modulator) used for steering a laser beam over large angles. Continuous steering over ±12.4° is achieved, controlled by the power of an infrared pump beam; This is a very large steering angle for a nonmechanical nondiffractive system.
