Abstract
The phase-modulating capability of a commercial LCTV has been measured and its application in a joint transform correlator, using a single spatial light modulator, is discussed. The maximum LCTV phase depth obtained is closed to (pi) /2 and a small cross-coupling amplitude modulation is observed. Simulation and experimental results are obtained for the phase joint transform correlator, where the wavefront error, due to the LCTV, is corrected with a phase conjugation technic.
