Stressed Liquid-Crystal Optical Phased Array For Fast Tip-Tilt Wavefront Correction, Bin Wang, Guoqiang Zhang, Anatoliy Glushchenko, John L. West, Philip Bos, Paul F. Mcmanamon
Philip J. Bos
A liquid-crystal optical phased-array technology that uses stressed liquid crystals provides a new type of tip-tilt wavefront corrector. It demonstrates a very fast time response (10 kHz) and high beam-steering efficiency (similar to 91%). The new technology presented here will allow for a nonmechanical, high-speed correction with simple device construction.
