摘　　要：针对批产化空间透射镜头短周期、高精度和高像质一致性的研制需求,研发了一种自动调整、在线检测、自主分析和自动校正波像差的自动装校系统。首先,设计了透镜自动调整方式和悬浮胶粘的结构形式,采用坐标投影将透镜失调量的测量值转换为调整装置的线性调整量,利用电机驱动调整装置的组合运动实现透镜自动调整。然后,设计了镜头调整检测集成平台和波像差校正模块,根据系统波像差测试结果自主分析透镜自由度调整量,并驱动调整装置运动实现透镜位置的补偿调整,通过均衡校正残留波像差的方式保证批次间像质的高一致性。最后,对20套批产化镜头进行自动装校实验,镜头研制周期为3天/套,透镜失调量控制精度优于10″和5μm,批次间相应视场调制传递函数最大偏差为0.026。实验结果表明,本系统可为批产化空间透射镜头装校提供一种高效的自动化研制途径。In order to obtain wide-range and high-precision remote sensing information,aerospace powers such as China,the United States,and many other European countries have adopted large-scale,multi orbit,and global coverage satellite deployment methods,and the space cameras are also developing in batches.Compared to traditional remote sensing cameras that only require some traditional imaging performance indicators,batch space cameras increase the requirements for shorter manufacturing cycles and higher image quality uniformity between batches.Due to the characteristics of large field of view,small size,and low cost,refractive lenses have been widely used in batch space cameras.At present,the precision centering error method is mainly used for the adjustment of space refractive lenses at home and abroad.The adjustment process is highly dependent on manual skills and experience.In addition,due to the random deviations of batch materials,lens processing accuracy,lenses adjustment tolerance and other factors,it is difficult to achieve high image quality uniformity of batch lenses while ensuring short adjustment cycle.Therefore,it is necessary to improve the assembly efficiency and quality uniformity of batch lenses by introducing more practical automatic alignment system.With the construction idea of“structural integration,adjustment automation,detection online and correction autonomy”,an automatic lenses alignment system with functions of automatic adjustment,online detection,automatic analysis and correction of wavefront aberrations was developed.Firstly,an automatic lens adjustment method was designed based on the centering error measurement.The measurement values of lens mis-adjustment were converted to the linear movement values of the adjustment devices by coordinate projection,and the automatic adjustment was realized by the combined movements of the adjustment devices driven by the motor.Then,according to the automatic adjustment mode,the lenses structure was designed,and the stability of structural mechanics wa
