Abstract

The quality of many images are affected by unknown distortions, such as the imperfections caused by atmospheric turbulence. This paper explores a technique for estimating unknown wavefront distortions in a short period of time, possibly even during real time. A time-space algorithm has been implemented in software as a tool for estimating and canceling the unknown distortions. The algorithm uses moments of an observed point spread function and searches a database of pre-calculated moments to estimate the wavefront.
