Research on test technology of high sensitivity and high frame rate of far ultraviolet spectroscopy

摘要

Importance of ultraviolet calibration is growing fast as ultraviolet payloads are wildly used in national space plan. Calibration device for UV radiation celestial body simulator is established especially for the calibration of instantaneous radiation parameters and high-sensitivity radiation parameters. Parameters such as spectral radiance, spectral irradiance can be calibrated from 200 ran to 400 ran. The uncertainty of spectral radiance is 15% (k=2) and the uncertainty of spectral irradiance is 20% (k=2) .The calibration device is perspective for its application in national defense system.
