Radiation Metrology Technology After Into 21 Century

Abstract

Based on analysing development of radiation measurement technology, new metrology research directions after into 21 century are introduced, including new method of radiation metrology transfer and high energy laser limit measurement. Blackbody radiation, cryonic radiometer, and synchrotron radiation ultraviolet value transfer system are described in value transfer methods. In laser limit measurement, measuring high-energy laser power with different methods is of great importance. Then some radiation measurement work in the First Scale Optical Metrology Station of the Commission of Science, Technology and Industry for National Defense is introduced, including spectral irradiance and radiance standard, blackbody radiation source standard, extended area blackbody calibration device, and spectral response measurement device of radiation detector, etc..
