提出了一种有利于空间外差光谱仪光谱复原的探测器筛选方法。通过仿真分析确定了影响空间外差光谱仪光谱复原的探测器响应参数,针对这些参数设计了相应的探测器筛选方法。利用设计的探测器筛选装置进行了探测器筛选实验,对实验数据进行处理和分析,从备选探测器中选取了最优性能的探测器。筛选测试后的探测器已经应用于星载空间外差光谱仪,并通过了一系列实验考核。

In order to screen a high-performance detector for spatial heterodyne spectrometer, a method of detector screening and testing is proposed. Parameters of detectors which influence the spectral reconstruction of spatial heterodyne spectrometer are determined by simulations, and the screen method based on these parameters are obtained. The experiments are conducted with the designed screening and testing setup. Through processing and analyzing the experimental data, the optimal array detector is chosen from the alternate detectors. The satellite- borne detector obtained by screening and testing has already been used in the spatial heterodyne spectrometer and passed a series of test evaluations.
