| Abstract: | Based on cross correlation coefficient and absolute difference algorithms and the principle of Hartmann Shack wavefront sensor, the feasibility of correlating Hartmann Shack wavefront sensor used for low contrast and extended object is studied according to the indoors solar granulation simulator. The results show that correlating Hartmann Shack wavefront sensor can be efficiently used to detect wavefront aberration for low contrast and extended object. |
