Closed-loop adaptive-optics system with a liquid-crystal television as a phase retarder.

Abstract

We present a closed-loop adaptive-optics system that uses a liquid-crystal television (LCTV) as a phase retarder. The system consists of a LCTV inserted into one leg of a Mach-Zehnder interferometer so that one measures the wave-front function by analyzing the interferogram using a video CCD camera and a computer and corrects the wave-front distortion by placing the conjugate function on the LCTV. Experimental results are presented.
