Abstract :
A point diffraction interferometer was used to examine the phase nonuniformity of a liquid-crystal television (LCTV). The resulting interference pattern was then binarized and written back onto the LCTV for phase compensation. A binary phase joint transform correlation experiment was performed using the binary phase corrected LCTV to demonstrate the applicability of this technique.<>
