Abstract

Regularization techniques and Fourier optics are combined to design a class of real time coherent optical processors, which exhibit considerable immunity to phase noise. Regularization and adaptive control is achieved by employing a piezo-electrically controlled displacement of one of the feedback mirrors. The processor has been used to obtain extrapolation of spatially limited objects imaged through a diffraction limited system.
