摘要
基于目前常用的光谱杂散光测试与修正方法,详细介绍了光谱杂散光矩阵修正法的核心内容——仪器的光谱杂散光矩阵的标定。在实验室搭建了杂散光矩阵测量装置,标定了前向临边成像光谱仪初样机的杂散光矩阵,在外场实验中验证了基于仪器杂散光矩阵的杂散光修正方法的精度。
Based on a brief introduction to the current methods of stray light testing and correction, the spectral stray light matrix calibration, which is the core content of the spectral stray light matrix correction method, is introduced in detail in this paper. Then, to calibrate the stray light matrix of the prototype of the forward limb imaging spectrometer, we set up a stray light matrix measuring device in the laboratory. Finally, the accuracy of the stray light correction method based on the stray light matrix of the instrument is verified in an external field experiment.
