title: Real-time joint transform correlator with phase conjugation for distortion correction.
abstract: A joint transform correlator has been demonstrated that incorporates phase conjugation in a BaTiO3 crystal to correct for distortions in a liquid-crystal television (LCTV) spatial light modulator. The optical arrangement permits real-time operation in spite of the relative slowness of the photorefractive effect. Correlation outputs displayed on a video monitor are illustrated for inputs to the LCTV from a video camera viewing a stationary scene. The sensitivity of the correlator to target rotation is also presented.
