摘要
从调制传递函数的观点出发,考虑振幅起伏相关性的影响,导出了在强湍流区自适应光学技术补偿光束畸变的斯特列尔比及补偿效率理论表达式。理论预计与实验结果相符。并且,对不要求完全补偿的情形,自适应光学在强湍流区也是适用的。
Based upon modulation transfer function, the Strehl ratio and compensation efficiency of an adaptive optical technique in the region of strong turbulence are discussed.The amplitude-fluctuation correlation is taken into account. Theoretical expreessions of Strehl ratio and compensation efficiency are derived. Calculations show that the theoretical predictions coincide with the experimental values very well. In the case of noncompelet compensation, the adaptive optical technique is useful even in the region of strong turbulence.
