ABSTRACT

At the Physikalisch-Technische Bundesanstalt, the National Metrology Institute of the Federal Republic of Germany, the traceability of non-contact temperature measurement to the International Temperature Scale (ITS-90) is realised without gaps over a temperature range from −170°C to 3000°C. In this paper the main calibration facilities for the calibration of radiation thermometers at temperatures above 1000°C and measurement of spectral radiance, the calibration of radiation thermometers at temperatures below 1000°C, the calibration of infrared thermographic cameras together with a method developed at PTB to correct the non-uniform response of sensor arrays, the calibration of infrared hyperspectral imagers for remote sensing, and emissivity measurement for industry and remote sensing are described. These facilities are tailored for different temperature ranges and different spectral ranges to meet the demand of industry and research for precise, practical non-contact temperature measurement.

摘要

在德意志联邦共和国国家计量研究所的物理技术学院，可实现无接触温度测量到国际温度标度（ITS-90）的可追溯性，并且温度范围从-170°C至3000℃。在本文中，主要的校准设备主要用于在温度高于1000°C时校准辐射温度计和测量光谱辐射度，在温度低于1000°C时校准辐射温度计，对红外热像仪进行校准以及在PTB上开发的方法为了纠正传感器阵列的不均匀响应，描述了用于遥感的红外高光谱成像仪的校准以及用于工业和遥感的发射率测量。
