Paper Abstract

Dynamically stable parallel image subtraction has been achieved using phase conjugate interferometry. We use a Michelson interferometer with an internally self-pumped barium titanate crystal as the phase conjugator for both arms. Various aspects of image subtraction, including intensity inversion and "exclusive or" logic operation are demonstrated. Device operation is insensitive to alignment and optical path length perturbations.
