超大相对孔径抛物面反射镜的补偿检验

Testing of paraboloid mirror with super relative aperture using compensator

在基于像差理论的基础上,对于超大相对孔径抛物面反射镜,提出了三片补偿镜和一片场镜的零位补偿检验方法,详细论述了补偿检验系统的设计过程,成功地设计了相对孔径为F0．6,口径为φ290 mm的抛物面反射镜的补偿检验系统,从整个设计的结果看出,检验系统的像差被很好的校正,完全达到衍射极限。

Based on third-order aberration theory, a method of null test using compensation that include three compensating lens and a field lens is put forward for paraboloid mirror with super relative aperture, and describes detailed the design process of compensation system. The testing system is designed successfully for a paraboloid mirror that relative aperture is F0.6 and aperture is Ф290 mm. The result of design, show that aberration of testing system is well corrected and the system reached to diffraction limit.
