本文阐述了变象管的测量红外灵敏度、本征红外灵敏度和使用红外灵敏度的物理意义及它们之间的差别。我们在文献[1]中,曾经通过测量、计算,予见到使用比较理想的红外滤光片,将使变象管的测量红外灵敏度成倍地提高,本文通过实验证实了这一结论。最后导出了两个重要的结论:一、主动式夜视仪的视距正比于探测器的测量红外灵敏度;二、探测器的测量红外灵敏度正比于红外滤光片的积分透过率或红白比。
This article describes the physical, meanings, and differences between infrared tubes, intrinsic infrared and infrared sensitivities. We have in the literature [1], once through the measurement, calculation, to see the use of the ideal infrared filter, will make the variable tube infrared infrared sensitivity increased exponentially, this experiment confirmed this conclusion. Finally, two important conclusions are derived: First, the line of sight of an active night-vision device is proportional to the infrared sensitivity of the detector. Second, the sensitivity of the detector to infrared sensitivity is proportional to the integral transmittance of the infrared filter or red and white ratio.
