对国内的红外热像仪系统瞄准线测试方法的探讨

摘要

Parallelism of optical axis and datum clamp plane for IR imager is discussed and its meaning is analyzed and summarized. Then, two typical domestic methods for parallelism of optical axis and datum clamp plane for IR imager are analyzed and their rigors, advantages and disadvantages are summarized. Finally, a more effective and reliable testing method is proposed. Its testing principle is more rigorous and its testing precision is higher.%从使用的角度出发分析了红外热像仪的系统瞄准线指标的重要性和计算方法，围绕如何对其进行准确检测介绍了国内两种典型的系统瞄准线测试方法，并对它们的优缺点进行了分析，对测试系统提出了改进意见。
