    • Abstract
  • The relation between spatial-temporal characteristic of atmospheric perturbation and several parameters of adaptive optics system is analysed in this paper.Some altitude-distribution models of atmospheric turbulence intensity and wind velocity are presented. According to these medels the atmospheric coherence length,the coherence time and the isoplanatic angle are calculated. The internal errors of an adaptive optics system are discussed. The typical value of each error is indicated. The Strehl ratio of the system is considered in last.
