摘要
When an adaptive optical system is used in an imaging system observing extended targets, a method of correlation can be used to find the relative movements of the sub-images in its Hartman-Shack waterfront sensor. To get a sub-pixel accuracy, a curve fitting method is presented. This paper describes the method in detail, and presents the simulations and experimental results. These results show an accuracy of 0.1 pixels rms.
