Paper Abstract

Liquid crystal spatial light modulators (LC SLM) are being applied as input devices in optical data processing systems, optical filters in optical coherent correlators and projection display devices. The methods of self-filtration of image in image and/or Fourier planes, including spectral, nonlinear, and other types of image filtration, are reported here. The methods are established both on high spatial resolution and nonlinearity of optical response to the input optical signal of LC SLM. A few optical schemes for input image self-filtration were experimentally realized with spatial light modulators based on monocrystalline semiconductors (GaAs, BSO, CdZnSeS), combining sensitivity, spatial resolution, and highly nonlinear modulation curve corresponding to most of the electro-optical effects used in LC SLM.
