双视场红外光学成像系统

一种双视场红外光学成像系统，其包括一中间固定装置( 1 )，所述中间固定装置( 1 )两侧分别设置有一红外光学成像系统。其中，所述红外光学成像系统包括主反射镜( 2 )、次反射镜( 3 )、会聚透镜组( 4 )及红外探测器( 5 )，所述主反射镜( 2 )设置在固定装置( 1 )一侧。所述会聚透镜组( 4 )设置在次反射镜( 3 )和主反射镜( 2 )之间，所述红外探测器( 5 )设置在固定装置( 1 )一通孔内，并位于会聚透镜组( 4 )的像平面上，而且所述次反射镜( 3 )、会聚透镜组( 4 )、主反射镜( 1 )以及红外探测器( 5 )共光轴。因此本发明双视场红外光学成像系统视场大，受温差影响小，且像差小，图像清晰且稳定，具有较佳的成像质量。

Double-view-field infrared optical imaging system

A double-view-field infrared optical imaging system comprises a middle fixing device (1). The two sides of the middle fixing device (1) are each provided with an infrared optical imaging system body. Each infrared optical imaging system body comprises a main reflection mirror (2), a secondary reflection mirror (3), a converging lens set (4) and an infrared detector (5), wherein the main reflection mirror (2) is arranged on one side of the fixing device (1). The converging lens sets (4) are arranged between the secondary reflection mirrors (3) and the main reflection mirrors (2); the infrared detectors (5) are arranged in through holes of the fixing device (1) and located on the image planes of the converging lens sets (4); and the secondary reflection mirrors (3), the converging lens sets (4), the main reflection mirrors (2) and the infrared detectors (5) share the same optical axis. Therefore, the double-view-field infrared optical imaging system is large in view field and is affected little by the temperature difference; and the optical aberration is small, an image is clear and stable, and the good imaging quality is achieved.
