为适应近年来越来越多的热象系统的研制和分析,我们对以前尚不能测量的红外系统透过率进行了一系列的实验,分析对比工作。从现已查到的国外资料来看,透过率测量主要有以下几种方法。 1.积分球法信号接收部分采用的是大面积、高灵敏度接收器。这是一种传统的测量透镜可见光波段,轴上透过率的方法,也可用来测量红
In order to adapt to the development and analysis of more and more thermal imaging systems in recent years, we conducted a series of experiments on the transmittance of infrared systems that have not been measured before, and analyzed and compared them. Judging from the foreign information that has been found, there are mainly the following methods for measuring the transmission rate. 1. Integral Sphere Method The signal receiving part uses a large area, high sensitivity receiver. This is a traditional method of measuring the visible light band of the lens, the transmittance on the axis, can also be used to measure the red
