Abstract
The technique of optical phase conjugation can be used to reconstruct a laser beam that has been aberrated on passing through a distorting medium. Reflection from a phase-conjugate mirror (PCM) produces a "time reversed" replica of the aberrated beam. The aberrations are removed when this phase-conjugate beam propagates back through the distorting medium, producing a time-reversed replica of the original beam.
