Abstract

In order to establish the standard transfer chain traceable to the absolute cryogenic radiometer and improve the absolute calibration accuracy of spectral radiation for optical remote sensor, an optical radiometric calibration method based on broadband monochromator light source is proposed and the corresponding system is developed. In the system design, not only the high-efficiency monochromator lighting system, low aberration off-axis paraboloid reflection optical path, high precision mechanical adjustment device and positioning device are adopted, but also the light source water-cooling system is used to effectively improve the performance of the system. The results show that the system has the characteristics of broadband, high precision and good stability, which provides an effective and feasible technical means for realizing the standard transfer of detector with high-precision.
