Paper Abstract
The Fourier transforming properties of coherent imaging
systems are well known and thoroughly developed. Optical spatial
filtering techniques for coherent imaging systems are also a well
developed field of study. Most of the advances in spatial
filtering techniques were developed for systems with a known set of
input characteristics. Once these filters were developed, they
were static and unable to change wih a new set of inputs
exhibiting a different set of characteristics. This paper will
present the theoretical basis and desiy of an adaptive coherent
imaging system using a two-dimensional spatial light modulator
(5124) in the frequency plane. A computer controller is used as a
feedback loop from the output plane back to the 5124. The filter
implemented by the SLM is developed by simulated annealing. This
iterative process enables the filter to adapt to a variety of
inputs and automatically optimize given sufficient iterations.
This paper will also present feasible applications of this
technique in image processing and pattern recognition.
