| 中文摘要: |
| 为提高航空相机识别目标能力，设计了一种应用于全景式航空侦查相机的可见光/红外双视场成像光学系统，可见光光学系统焦距为200 mm/400 mm，相对孔径为1：8.8，视场角为9.4°×7°/4.7°×3.5°。红外光学系统焦距为117 mm/234 mm，相对孔径为1：4，视场角为9.4°×7.5°/4.7°×3.76°。该光学系统利用物像交换原则采用轴向移动变倍方式，设计结果表明，光学系统成像质量接近衍射极限，可以满足实际使用需求。 |

| In order to improve aviation investigation to identify the target probability and meet the combat demand of the troops,in this paper,we design a visible-light/infrared dual-field-of-view optical system which applies for panoramic aerial camera.The focal length of the visible-light optical system is 200 mm/400 mm,the relative aperture is 1:8.8,and viewing angle is 9.4°×7°/4.7°×3.5°.The focal length of infrared optical system is 117 mm/234 mm,the relative aperture is 1:4,and viewing angle is 9.4°×7.5°/4.7°×3.76°.The optical system uses the variable magnification principle of object image exchange.The results show that its image quality is close to the diffraction limit,which satisfies the needs of practical applications. |
