Abstract

The complex transmittance and selected physical parameters of liquid-crystal displays removed from a commercially available Sanyo video projector are studied. The phase modulating behavior and phase and amplitude coupling are determined as function of the video drive signal and the polarizer/analyzer configuration. The suitability of the LC displays as input modulator in a joint transform correlator setup is shown. Correlation experiments with input signals taken from an original Babylonian cuneiform inscription are carried out.
