利用横向谱滤波方法,给出研究自适应光学非等晕性的一般关系式。在特殊场合,对这些一般关系式进行解析求解,获得与经典理论一致的结果。进一步定义了与自适应光学系统非等晕性有关的一些特征量。在一般应用场合,这些一般关系式只能求得数值解。以激光测月自适应光学系统为例,说明了所述一般关系式在研究自适应光学非等晕性问题方面的应用。

The general formularies to study the anisoplanatism of adaptive optical systems are constructed by the transverse spectral filtering method. At some peculiar situation, these formularies can be expressed to explicit form, and the classical scalar law and the relevant characteristic scale can be obtained and generalized. While in general, only numerical values can be obtained. As an example, the lunar laser ranging system with an adaptive optics (AO) to correct the uplink beam is used to explain the use of these formularies to study the anisoplanatism of AO systems.
