共形光学系统设计研究*

摘要

共形光学整流罩在保证了光学指标的前提下，与后端的其他结构外形轮廓平滑连接，从而提高了飞行器空气动力学的性能，在航空航天领域具有重要的应用价值。然而，采用特殊面型的整流罩给共形光学系统的像差校正以及加工、检测方面带来了极大的挑战。本文首先分析了共形整流罩像差特性，并在此基础上介绍了两种典型的光学设计。%　　A conformal dome is typically an optical window that conforms smoothly to the external shape of a system platform to improve the performance of aircraft aerodynamics, based on the premise of conformal optical system to ensure the optical indicators. And it has important in the field of aerospace. However, adopting domes with special surfaces brings great challenge to the aberration correction, processing and detection. This paper first analyzes the conformal fairing aberration characteristics. Then it introduces two typical optical designs.
