We elaborate the mechanism of STED and the conditions of depletion. The formula of STED microcopy resolution is deduced through effective point spread function (E-PSF). The STED system resolution is mainly dominated by the quality of the fluorescence depletion patterns in the focal plane. The depletion pattern is mainly affected by STED beam intensity  polarization  phase plate  primary aberrations  STED pulse shape  pulse duration and delay time. In this paper  we found related models and simulate the relationship between the depletion patterns and the parameters  and put forward effective approach to enhance the system resolution. 2010 SPIE.
