摘要
采用波前各阶Zernike成分孔径滤波函数方法,推导了当观测目标与信标不在同一方向时所产生的非等晕误差的表达式,同时利用该表达式进行了对自适应光学系统倾斜校正后的波前残余误差数值模拟。此外还首次对天文干涉仪中大气湍流活塞效应引起的活塞角非等晕误差进行了研究分析,为以后实际利用自适应光学校正工作提供理论参考。
This paper uses the filter functions of Zernike components to derive the formula for the anisoplanatic error, which arise from the offsets between observed objects and guiding stars. At the same time, numerical results from the formula are given for the residual wave-front errors in adaptive optical systems after the correction for the tilting effects. Furthermore, this paper studies for the first time the expression to correct differential piston angular anisoplanatism interferometers. These results may provide in adaptive optical observation through astronomical optical theoretical basis for the practical error correction of adaptive optical systems.
