该文选取光纤消逝波传感器为研究对象,测量了纯净水、球形玻璃碳悬浊液和石墨悬浊液的常规透过谱和光纤消逝波谱。研究发现对于片状石墨悬浊液和球形玻璃碳悬浊液透过谱,透过信号的强度和形状存在差别,我们从悬浮颗粒的形状、大小以及消逝波的穿透深度等方面给出了合理解释。

This paper is focused on the application of fiber evanescent sensors in extraction spectral information in turbid liquid. The bulk transmitted spectra of graphite flakes and glassy carbon suspension with various concentrations were recorded. The reasons for different influences of graphite flakes and glassy carbon particles turbid liquid on transmitted spectra were analyzed on the basis of particles morphology, size and transmitted depth of evanescent field wave.
