Abstract: By simulating multiple modes and uneven energy distribution of actual light beams,the relationship between PSD localization and above mentioned uneven energy distribution is established in this paper,and thus,theoretically and experimentally justifies that PSD localization is solely subject to the balance center of light beam spots.
