infrared radiometer

基本解释

In calibration of a infrared spectrum radiometer, we calibrate an infrared radiometer by measuring on various temperatures of the blackbody in order to reduce error.
在红外光谱仪的定标中，为了减小误差，可以选取多温度点的测量来进行定标；
Measurements can be made with an infrared radiometer. Blackbody radiation at the same temperature of the object is obtained using a cylindrical direct reflection cavity.
测量中使用了红外辐射计，并用圆柱形镜反射腔获得温度同地物相同的黑体辐射，并由已知比辐射率的参考板标定环境辐射。
Pyroelectric detector and fast respond infrared radiometer are used in the system to carry on the measurement, and effective data processing method is adopted to improve the test accuracy.
该系统分别采用热释电探测器和快速响应的红外辐射计进行测量，并采取了有效的数据处理方法，提高了测试精度。

The pictures come from the Visible Infrared Imaging Radiometer Suite (VIIRS) satellite, and have been referred to as "The Black Marble" in reference to the famous "Blue Marble" daylight pictures.
