Abstract

Binary adaptive optics involves using a simple two-state algorithm for wavefront correction. The technique lends itself to implementation using ferroelectric liquid crystal spatial light modulators (FLC-SLMs) as half-wave and quarter-wave phase shifters. In this paper we demonstrate further the effect of half-wave and quarter-wave correction, we compare the ideal performance with conventional analogue adaptive optics and we discuss the relevant optical properties of FLC-SLMs.
