Imaging spectrometer radiation parameter and imaging parameter calibration device and method

The invention provides a visible near-infrared imaging spectrometer radiation parameter and imaging parameter calibration device and method. The calibration device and method use a high-stability large-caliber standard integrating sphere light source with a target interface to be combined with a large-caliber collimator to form collimation radiation which is received by a measured visible near-infrared imaging spectrometer. A standard spectroradiometer calibrated by a spectral radiance standard lamp calibrates the spectral radiance of the exit of the integrating sphere light source and the collimation radiation respectively, so as to achieve full-band radiance high-accuracy calibration of the visible near-infrared imaging spectrometer of a camera system and a telescope system. The measuredvisible near-infrared imaging spectrometer is used to image a series of standard targets mounted on the target interface of the large-caliber standard integrating sphere light source, so as to realize imaging parameter calib
