Background:

  • Previous work utilized dynamic range compression with nonlinear deconvolution for image correction.
  • The technique involved joint transformation of distortion impulse response and image in a photorefractive setup.
  • The Fourier transform of a pumped reference beam yielded the deconvolved image.

Purpose of the Study:

  • To extend dynamic range compression techniques to handle spectrally variable distortions.
  • To enable retrieval of distorted signals in environments with very high noise.
  • To improve image resolution recovery without requiring a very high beam ratio.

Main Methods:

  • Implementation of spectrally variable dynamic range compression.
  • Utilizing nonlinear deconvolution and photorefractive two-beam coupling.
