摘　　要：针对一个Golay3结构的稀疏孔径望远系统,结合其总体结构及各部分组成光路的特点,提出了一种全光学系统装调方法,首先利用数值计算方法分析了光学系统各组成部分装调误差引起的系统像差,确定了影响装调质量的误差分布情况,并在此基础上,规划了整个稀疏孔径系统装调步骤。装调完成后,利用干涉仪进行了检测,结果显示该系统各组成部分的波前误差RMS值均优于λ/8(λ=633 nm),装调结果表明该稀疏孔径望远系统满足理论设计指标,能够达到工作要求。For a Golay3 sparse aperture telescope system,an all-optical system assembling scheme is proposed based on its overall structure and the optical path of each part. Firstly,the system aberration caused by the assembly and adjustment errors of each component of the optical system is analyzed numerically,and the error distribution that affects the assembly and adjustment quality is determined. On this basis,the whole system installation and adjustment steps are planned. After the installation,an interferometer is used to detect the alignment effect. The results show that the wavefront error RMS values of each component of the system are better than λ/8( λ = 633 nm). The assembling results show that the sparse aperture telescope system meets the theoretical design index and can meet the working requirements.
