Abstract

In this paper we propose a new totally optical approach to the implementation of iterative algorithms for image restoration. A phase conjugating mirror (PCM) is employed as an amplifying element to implement a coherent optical feedback system capable of performing iterative operations on a spatially modulated input beam. Three systems are suggested. Their optical analysis is performed. The obtained results indicate that each system is capable of restoring linearly degraded images.
