Abstract
A regularized coherent optical processor, exhibiting considerable immunity to phase noise, is designed and used to achieve resolution beyond the diffraction limit. Regularization is achieved by means of a piezoelectric displacement of one of the feedback mirrors. The optical processor is used for real-time object restoration from noisy, diffraction-limited images. A software implementation of the regularized algorithm, for the case of a two-slit object, shows good agreement with the results obtained from the optical processor.
