固体探测器用于光谱观测中的噪声及消除方法

Noises in Observing Stellar Spectra Using Solid-State Detectors and Method to Reduce Them

本文以云南天文台CCD-Coude光谱系统中的云台1号CCD系统为例,讨论了CCD等面阵或线阵固体探测器件用于大色散光谱观测引起的噪声及消除的方法,重点讨论了平场的方法。

Taking the No. 1 CCD system of Yunnan Observatory, attached to CCD-Coud'e spectrographic system, as an example, the noises induced by area (CCDS) or linear solid-stote detectors used for the spectra observations with large dispersion and the methods to reduce those noises, mainly the method for flatfielding are discussed.
