四、快扫干涉仪的应用1.前言在过去十年中,快扫干涉仪所进行的研究大多数是弱光源光谱的测定,而不是吸收光谱测定。主要原因是这项技术是用在一般光谱法即使不是不能解决也是极为困难的一些问题上。另外,弱信号的数据处理比强信号稍为容易些,因为它只有一个小的动态范围需用数字记录,而采用白炽光源产生干涉图时,即使用
Fourth, the application of fast scanning interferometer 1. Introduction In the past decade, most of the research conducted by fast scanning interferometer is the determination of the weak light source spectrum, rather than the absorption spectrometry. The main reason is that this technique is used on some issues where the general spectroscopy is extremely difficult if not impossible to solve. In addition, weak signals are slightly easier to process than strong ones because they require only a small dynamic range for digital recording, and when using incandescent light sources to generate interferograms,
