大扫描视场红外椭球形整流罩光学系统设计方法

应用椭球形整流罩的飞行器具有良好的空气动力学特性，但由于头罩的非旋转对称结构特性，后续红外搜索/跟踪成像系统难以同时实现大扫描视场与良好成像质量.为解决这一难题，提出一种基于拱形校正元件和动态校正器的椭球形整流罩光学系统设计方法，使用该方法设计的中波红外头罩光学系统具有±54°的超大扫描视场，且成像质量在整个扫描和瞬时视场内接近衍射极限.

Abstract

The aircraft with an elliptical dome acquires excellent aerodynamic performance, but the non-rotationally symmetric structure characteristic of the dome makes the airborne infrared search/track system difficult to meet the requirements of wide field-of-regard (FOR) and high imaging quality at the same time. In order to overcome this problem, a design method for the elliptical dome optical system based on the combination of an arch corrector and a dynamic corrector was proposed. A mid-wave infrared optical system with an ellipsoid dome was designed as an example. The system has a super wide FOR of ±54°, and the imaging quality of the system approaches to the diffraction limit across the entire FOR and instantaneous field-of-view.
