摘要: 以多光束模拟实际光束中的多模式及能量分布不均的现象,建立了PSD定位与上述能量不均匀之间的关系,从而从理论和实验上均验证了PSD定位只取决于光斑能量重心.

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.
