摘要
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.
Novel conformal window can enhance the aerodynamic performance of aircraft obviously. Due to the surface complexity of these conformal windows,the measuring of conformal windows is infeasible by using the conventional optical measurement technique. In this paper,we describe a new sub-aperture stitching method for conformal measurement,and introduce the design of this technology. Based on the theory of compensation method,a compensator is designed for a 70mm aperture conformal window,of which the final residual wavefront error(RMS) is 0. 0515λ(λ = 632. 8nm).
