在红外辐射测量工作中,红外辐射计响应度的精确定标是极为重要的。一些文献提出了红外辐射计响应度的基本概念和常用的定标方法。但是,其中有的没有考虑各种背景或干扰辐射的影响,有的则是在处理上受到许多限制,实际工作中感到困难.本文系统地论证了在红外辐射计响应度定标工作中,完全消除各种背景和干扰辐射影响的远源精确定标原理,并得到了辐射计三种响应度的分析表达式。以及简便的定标测量与计算方法.
In the infrared radiation measurement work, the accurate calibration of the infrared radiometer responsivity is extremely important. Some documents put forward the basic concept of infrared radiometer responsivity and commonly used calibration methods. However, some of them do not consider the influence of various backgrounds or interference radiation, while others suffer from many limitations in handling and find it difficult in practical work.This paper systematically demonstrates that in the calibration work of infrared radiometer responsivity, Eliminate all kinds of background and interfere with the impact of radiation far precise calibration principle, and the radiometric three responsivity analysis expression. And simple calibration measurement and calculation methods.
