Abstract:

On the focal plane of the telescope and detector, relationships between the r.m.s contrast in the solar granulation and pixel scale of the system are analyzed. In different pixel scalethe effectiveness of the tracking algorithm is studied. Future more, the related experimental results are given. The results show that as the decreases of the pixel scale and the r.m.s contrast in the solar granulation, the effectiveness of the tracking algorithm gets better.

Key words: solar granulation, r.m.s. contrast, pixel scale, the tracking algorithm
