摘要共形整流罩的气动光学像差是一种难以校正的光学像差，会引起严重的成像质量下降。波前编码（WFC）成像技术包括光学和数字处理步骤，以获得最终的高质量图像，并可用于控制光学像差。本文提出了一种基于WFC技术的AOACD校正策略。利用ANSYS软件对共形整流罩进行了热-结构仿真。利用CODEV软件分析了气动光学效应对共形光学系统性能的影响。然后，在共形光学系统的光瞳面插入一个典型的广义立方相位掩模，以抑制其气动光学像差。仿真结果表明：（1）图像退化主要是由共形罩的折射率分布引起的，而不是由其变形引起的;（2）利用WFC技术可以有效地抑制AOACD。这项工作在共形光学和气动光学中具有重要意义。
Abstract The aero-optical aberration of conformal dome (AOACD) is difficult to correct and would cause serious image degradation. Wavefront coding (WFC) image technique includes the optics and the digital processing steps to achieve the final high-quality images and it can be used to control the optical aberrations. In this paper, a strategy for correcting the AOACD is presented based on WFC technology. The thermal-structure simulation results of the conformal dome are obtained by using ANSYS. The performance degradation of the conformal optical system affected by aero-optical effect is analyzed by using CODEV. Then, a typical generalized cubic phase mask is inserted into the pupil plane of the conformal optical system to suppress its aero-optical aberration. The simulation results show that (1) the image degradation is mainly caused by the refractive index distribution of the conformal dome rather than its deformation; (2) the utilization of WFC technology could suppress AOACD effectively. This work is of consequence in conformal optics and aero-optics.
