Paper Abstract

We propose a phase coding technique for signal recovery of distorted images, and we demonstrate our results through computer simulations. In our demonstration we use two forms of distorted images: (1) a misfocused image and (2) a clean image distorted by passage through a thin aberrating medium. Our results show that even though only a portion of the distortion information was used, we can still recover the original image with a low level of additive noise. The proposed technique opens up the possibility of using all the available types of spatial light modulators for these purposes.
