Abstract

The invention relates to the technical field of optical testing equipment and discloses a spectral radiation luminance responsivity measurement system. The system comprises a vacuum ultraviolet lightsource, a vacuum ultraviolet monochrome beam splitter, a vacuum ultraviolet uniformizing device, a reference radiation luminance meter, a switching device, a controller and an oil-free vacuum chamber,wherein the vacuum ultraviolet light source is used for emitting vacuum ultraviolet light radiation; the vacuum ultraviolet monochrome beam splitter is used for carrying out beam-splitting processingon incident vacuum ultraviolet light radiation and then outputting light radiation with a predetermined wavelength; the vacuum ultraviolet uniformizing device is used for carrying out uniform processing on the output light radiation with the predetermined wavelength; the switching device is used for carrying out switching between alignment of the reference radiation luminance meter with the vacuum ultraviolet uniformizing device and alignment of a to-be-calibrated radiometer with the vacuum ultraviolet uniformizing device; the controller is used for calculating spectral radiation luminance responsivity of the to-be-calibrated radiometer according to radiation luminance values measured by the reference radiation luminance meter and the to-be-calibrated radiometer separately; and the oil-free vacuum chamber provides a vacuum environment, thereby accurately obtaining the spectral radiation luminance responsivity of the to-be-calibrated radiometer.

Description

technical field [0001] The invention relates to the technical field of optical testing equipment, in particular to a spectral radiation luminance responsivity measurement system. Background technique [0002] The working spectrum of the vacuum ultraviolet spectroradiometer is an important characteristic spectrum of space material composition, and it can give the vacuum ultraviolet spectrum information of the detection target at the same time.
