共形光学设计研究

符合空气动力学的导引头整流罩都是流线型的面型,由于这些面型破坏了光学系统的对称性,与导引头成像光学配合时会带来严重的像差,使成像质量下降。所谓共形光学设计就是在整流罩和成像光学系统之间加入校正系统,用校正系统校正整流罩所带来的像差,以便获得良好的成像质量。介绍了共形光学设计的概念,讨论了设计原理,分析了热变形的影响,并给出了一个设计实例。

Design and study of conformal optics

The dome surfaces that accord with aerodynamic theory are always streamlines.However,these conformal dome surfaces are usually interferential with the symmetry of the optical system,which may produce severe aberrations and may reduce the resolving power of the system.A corrector system,which is between the conformal dome and the optical system,can be used to correct the aberrations produced by the conformal dome surfaces.The basic ideas,the design method and the thermal aberrations analysis of conformal dome surfaces are presented.A design example is also presented.
