FT光谱学中波数取值范围对复原谱影响的分析

ANALYSIS OF THE RECONSTRUCTED SPECTRUM AFFECTED BY THE REGION OF WAVENUMBER IN FT SPECTROSCOPY

文献１中作者给出可以利用Ｈｉｌｂｅｒｔ—Ｓｃｈｍｉｄｔ理论准确复原光谱的两个条件，即①σｍｉｎ／△σ＝ｋ（ｋ＝１，２，３……）和②０≤０ｍｉｎ／△σ≤１／Ｎ做进一步分析，指出复原谱变形的根本原因，并得出ＦＴ光谱术中复原谱随波数取值范围变化的规律及开始发生变形的位置。

In the previous paper1,the authors presented two conditions with which the spectrum canbe recovered successfully with Hilbert Schmidt’s theory.In this paper,further discussion of theconditions is made by means of Bessel function. The reason and the regulation of the deformation ofreconstructed spectrum when the region of wavenumber is different are also presented.
