傅里叶光谱仪中的切趾和分辨本领

The Apodization and Resolution in Fourier Transform Spectrometry

本文研究了傅里叶光谱仪中切趾对分辨本领的影响。计算表明,切趾不一定导致分辨本领的下降。选择性能优良的切趾函数,甚至可使切趾后的分辨本领高于未经切趾的分辨本领。为分辨两条靠得很近、强度相差甚大的谱线提供了一种方法。

This paper studies the effects of apodization on resolution inFourier-Trarsform Spectrometry. Results show that descent of resolution by apo-dization could be avoided. The resolution, if the apodization functions of fineperformances are selected, can be better than that of the unapodized. A methodfor resolving lines of unequal intensity has been herewith provided.
