Abstract
The capability of an inexpensive liquid-crystal TV (LCTV) to modulate both coherent and incoherent IR light is reported. Experiments demonstrating light modulation for wavelengths between 0.8 and 1.1 microns have been performed. Potential applications to dynamic 3-5 and 8-12 microns IR scene simulators, compact joint transform correlators, and novel electron trapping processors, are described.
