Abstract
An optical light valve system 10 for providing an amplified phase conjugated replica S.sub.1 * of a potentially low intensity phase aberrated optical signal beam S.sub.1 is disclosed herein. The optical light valve system 10 of the present invention includes a reference beam source 17 for providing a coherent reference beam R having first and second components of first and second polarization states, respectively. Further included is a signal beam source 15 for providing a coherent signal beam S of the first polarization state. An improved optical light valve 20 phase conjugates the second component of the reference beam in response to the aberrated beam S.sub.1 *.
