Radiation self-calibration system applied to spectrum scanner

The invention discloses a radiation self-calibration system applied to a spectrum scanner, which belongs to the field of spectrograph calibration, and comprises a support frame, a plurality of x-axis motion guide rails arranged in the support frame, a black box fixed on the support frame, and four sets of light sources uniformly distributed and penetrating through the top of the black box, the spectrograph is arranged in the middle of the four sets of light sources and penetrates through the top of the black box, the diffuse reflection plate combination is located in the black box and fixed to the supporting frame, illumination of a real solar spectrum is simulated, a sample is tested by completely sealing the black box, interference of the external environment is reduced, and therefore the testing accuracy is improved. 本发明公开了一种应用于光谱扫描仪的辐射自定标系统，属于光谱仪定标领域，本发明包括支撑架，设置于所述支撑架内数个x轴运动导轨，固定于所述支撑架上的黑箱，均匀分布并透过所述黑箱顶部的四套光源，设置在所述四套光源中间并透过所述黑箱顶部的光谱仪，位于所述黑箱内部并固定在所述支撑架上的漫反射板组合，本发明通过模拟实太阳光谱的光照，且样品完全封闭黑箱进行测试，减少外界环境的干扰，在从而提高测试
