摘要 利用横向谱滤波方法给出了研究自适应光学几何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,可获得与经典理论一致的结果;一般情况下,则只能求得数值解。以离焦分量也由自然信标子系统校正的特殊激光导星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几何非等晕性方面的应用。 The general formulae are constructed for studing the geometric anisoplanatism of an adaptive optics by the transverse spectral filtering method.At some peculiar situations,these formulae can be expressed to classical explicit form.while in general only a numerical value can be obtained.As an example,these formulae are used to study a special laser guiding star adaptive optical system whose defocus mode are also be corrected by the natural stars, besides the tip-tilt modes as the general laser guiding star adaptive optical system.
