使用新型的特殊整流罩窗口可以明显地提升飞行器的空气动力学性能,但由于这种共形窗口光学表面的复杂性,传统的非球面检测技术已经较难满足要求.本文提出了一种新型子孔径拼接检测技术,在建立新的检测原理基础上,还重点介绍了这种检测方法的设计.同时基于补偿法的原理,文中还针对一个口径70mm的共形窗口,设计了相应的特殊补偿器,其最终剩余波像差(RMS)为0.0515λ(λ=632.8nm),可以满足实际使用要求.
However, due to the complexity of the conformal window optical surface, the traditional aspheric surface detection technology has been difficult to meet the requirements by using the new special fairing window.This paper presents a new type of sub-surface Based on the establishment of a new detection principle, the design of this detection method is also introduced emphatically.At the same time, based on the principle of compensation method, a conformal window of 70mm in diameter is designed and a special compensator , The final residual wave aberration (RMS) of 0.0515λ (λ = 632.8nm), to meet the actual use requirements.
