Abstract

Liquid Crystal Televisions have received extensive attention in the literature for use as input and Fourier plane devices in joint transform correlators, and for use in other optical processing architectures requiring television rate inputs. The device has also been used in incoherent optical neural network systems at Penn State University. Recent research has also investigated the hybrid phase and amplitude modulating properties of the LCTV in a joint transform correlator. These properties will now be applied to the well known Vander Lugt matched filter correlator. The results of employing the LCTV as a phase-only input device for making and addressing photographic matched filters is presented. Experiments using the LCTV as both the input and filter plane modulator in a mixed phase and amplitude mode also is discussed.
