Abstract

The phase conjugation imaging technique has the capability for producing diffraction-limited resolution even in severely aberrated imaging systems. In this technique, various beams are mixed in a non-linear medium. An object-bearing beam, passing through the medium, generates a conjugate beam u*, which retraces the path of the original beam u, and the aberrations in u* are then compensated by the aberrations of the imaging system. This process, carried out in real time, is similar to a process developed in static holography in 1965.1–3
