摘要
通常的光多通道分析仪(OMA)存在着同时谱宽与分辨率的矛盾.本文所述方法,在不减小谱宽的前提下,可将该分析仪光谱分辨率提高1～2量级,使之可适用于高分辨率谱研究.
The optical multichannel analyzer (OMA) is a modern instrument for mesuring spectra. But there is a contradiction between the spectral resolution and the mesurable width of simultaneous spectra. In this paper, a method has been given out which can enhance the resolution ten times or even one hundred times without reducing the width of simultaneous spectra. The high resolving spectra of an OMA system can be easily obtained with this method.
