在红外技术中,黑体是一种有用的热辐射参考源,红外器件参数检测和红外整机性能评价的精度和一致性,很大程度上均依赖于辐射数据的准确性。经验指出,制造一个具有达到黑体特性的辐射标准源,比建造任何相同精度的非黑体源(如标准灯等)简单得多。因此黑体辐射标准源,广泛用于辐射仪器绝对测量的标定;用于标定红外热象仪和红外测温仪的温度;用于标定红外辐射计、红外和激光能量计、功率计的辐射能量和辐射功率;用于标定光度计、高温计的辐射功率和辐射温度等。辐射源的光谱辐射度分布应符合不同温度
In infrared technology, blackbody is a useful reference source for thermal radiation. The accuracy and consistency of infrared device parameters testing and infrared machine performance evaluation are largely dependent on the accuracy of the radiation data. Experience has shown that it is much simpler to create a radiation standard source that has the characteristics of a blackbody than any blackbody source of the same precision (such as a standard lamp, etc.). Therefore, the standard blackbody radiation source, widely used in the absolute measurement of radiation instruments calibration; used to calibrate the infrared thermometer and infrared thermometer temperature; used to calibrate the infrared radiometer, infrared and laser energy meter, power meter radiation energy and Radiation power; used to calibrate the photometer, pyrometer radiation power and radiation temperature. Radiation source spectral radiance distribution should be consistent with different temperatures
