太阳光谱仪用探测器的研究

A RESEARCH ON THE DETECTORS FOR SOLAR SPECTROGRAPHS

观测太阳光谱所使用的探测器,在选型与使用上有其特殊性.结合云南天文台太阳光谱仪,首先建立了太阳光谱仪分光流量的计算机模型,并通过观测实验对该模型进行了检验.利用该模型计算了云南天文台太阳光谱仪各可见光及近红外波段的太阳光谱分光流量,在此基础上,详细讨论了太阳光谱仪用探测器的选型方案,以及观测中的注意要点.

The selection and application of detectors for solar spectrograph described in this paper are more or less different from those in other works.For use at the solar spectrograph of Yunnan Observatory,the authors have built a model to estimate the spectral fluxes of solar spectrograph with computer and confirmed the result with observations.The spectral fluxes in visible and near infrared bands were calculated for the same spectrograph.Based on these results,the authors have discussed the detectors in details and summed up the processes in observation where some additional comments are needed.
