An optical architecture based on optically addressed amorphous silicon ferroelectric liquid crystal spatial light modulators has been built and demonstrated for optical iterative processing of two dimensional images. An optical ring in which a two dimensional optical delay line has been introduced, allows control of the cycling rate of the optical iterative processor from a few Hertz to up to 15 kHz. Potential applications for real time optical iterative processing includes scaling and rotation for optical based ATRs, optical fractal analysis, optical wavelet transform, and optical artificial neural network implementations.
