摘　　要：为了更好地对大视场主动光学望远镜进行调控。阐明了基于内外部度量系统对望远镜中调节组件进行检测定标的基本原理。对大视场主动光学望远镜定标过程进行了误差分析,并利用桌面实验实现了大视场主动光学望远镜运动部件检测方法的原理贯通。实现了非衍射均匀分光,克服了衍射分光杂散条纹多、分光角小的缺点,分散角高于100°,精度优于15μm,角度精度优于3″,基于波前传感进行标定的精度优于10μm,可有效提升大口径大视场望远镜调节元件的检定精度以及望远镜最终的成像质量。To better control large field of view active optical telescopes,this paper explains the basic principles of detecting and calibrating the adjustment components in telescopes based on internal and external measurement systems.Error analysis is performed on the calibration process of large field of view active optical telescopes,and the principle of the detection method for motion components of large field of view active optical telescopes is demonstrated through desktop experiments.Non-diffractive uniform beam splitting is achieved,overcoming the disadvantages of diffractive beam splitting,such as multiple stray fringes and small splitting angles.The dispersion angle is higher than 100°,with an accuracy better than 15μm and an angular accuracy better than 3″.The calibration accuracy based on wavefront sensing is better than 10μm,which can effectively improve the calibration accuracy of the adjustment elements of large-aperture,large field of view telescopes and ultimately enhance the imaging quality of the telescopes.
