25 October 1993 Complex characterization of the Epson liquid crystal television
Author Affiliations +
The complex transmittance of an Epson liquid crystal television was determined, as a function of the video drive signal. Several different operating configurations of the LCTVs were established, and their usefulness as operating modes for spatial light modulators in the input- and-filter-planes of a hybrid correlator is discussed. A high-stability phase measurement scheme was developed to determine the operating curves, and this system is presented. The transient response of the liquid crystal television to field-rate changes in the video signal is also presented. It is observed that the switching speed of the liquid crystal molecules presents an obstacle to the operating speed of these devices.
