摘要
在前一篇论文中,我们提出了利用法布—珀罗干涉仪(以下简称F—P干涉仪)研究光谱线超精细结构的一种新方法。在本文中我们将就表征F—P干涉仪特性的二个参量——自由光谱范围与分辨本领,把它与经典方法,作一理论上的分析与比较。其结论是:二者都必须遵守自由光谱范围。但在相同条件下,我们方法所能达到的分辨本领要比经典方法提高一倍。
A new method was suggested for studying the spectral line fine structure using Fabry- Perot interferometer in earlier paper. The two parameters characterized Fabry- Perot interferometer-free spectral area and resolution in the new method are compared with that in classical method in this paper. The conclusion shows that the both must observe free spectral area, but the spectral resolution of bur method is twice as high as classical one in the same conditions.
