Abstract

An adaptive optics system and method for providing wavefront aberration compensation with both phase reversal and amplitude preservation. Two operational modes, namely, a transmission mode and a compensated imaging mode, are available. Two spatial light modulators, preferably liquid crystal light valves (LCLVs) are operatively connected in tandem. Each LCLV has an associated feedback loop. One LCLV acts upon the phase aberrations in an input aberrated beam and the other LCLV acts upon the amplitude information in the aberrated beam. Alternative embodiments are also disclosed.
