Abstract

In this paper, correlation tracker for tilt-correction adaptive optical system at Solar Tower of Nanjing University built by the Institute of Optics and Electronics, Chinese Academy of Sciences, is described. The absolute difference algorithm is used to detect the image motion in the correlation tracker. The hardware configuration and timing of the correlation tracker are shown in detail. Furthermore, the experimental results are presented.
