【摘要】 针对导弹红外成像系统调试和测试的需要,设计了一种折射式红外平行光管。平行光管由准直物镜、红外靶、红外靶温度控制系统和镜筒等部分组成。准直物镜采用柯克3片式结构,且为像方远心光路,红外靶由镂空的铜板靶面和靶面后面的黑体组成,红外靶控制系统控制红外靶温差在0.2~8℃可调。对准直物镜的成像质量进行了分析,并给出了红外靶温度控制原理图。更多还原

【Abstract】 A refractive infrared collimator was designed for the adjustment and measurement of the infrared imaging system in the missile. The collimator consists of a collimating object lens, an infrared target, a temperature controlling system for the target and a tube. The collimating object lens employs Cooke triplet with a telecentric optical system in the image field. The infrared target includes a copper area and a black body behind the target area. The temperature controlling system can vary the temperature difference of the target between 0.2~8 ℃. The imaging quality of the collimating object lens is analyzed and the principle of the temperature controlling for the target is present.更多还原
