Radiometric calibration of infrared detectors and thermal imaging systems

摘要

Abstract: The paper describes the establishment of an infrared spectral responsivity scale at NPL with an uncertainty of 1.6% and the development of facilities to characterize the optical properties of infrared detector, arrays and cameras. The paper will illustrate the use of the calibration facilities with examples of uniformity, linearity and spectral responsivity measurements on a range of detectors.!8
