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 visiblelight/infrared dual-field-of-view optical system which applies for panoramic aerial camera. The focal length of the visibl^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.
