摘要
阐述了阶梯光栅光谱仪的工作原理和成像特征,分析了阶梯光栅光谱仪存在特殊光栅响应的原因以及给定量探测带来的影响。在此基础上,有针对性地提出一种基于标准灯的光栅响应的校准方法,校准后可以给出不同波长信号强度的真实分布关系,给光谱定量分析提供了现实依据。
The working principle and imaging identity of the echelle spectrograph was interpreted. The reason for the existing of the special grating response in the eehelle spectrograph and the effect on the work of quantitative detection. In this basis, a calibration method for the grating response based on the standard lamp was presented. It can give the real distributed relationship of the spectra-line intensity in different wavelength with calibration and offer the realistic basis for spectrum quantitative analysis.
