摘要
:本文提出了一种用于拉曼光谱研究的新型毛细管/双光纤传感器,对传感器构型和特性进行了研究,并将其用于四氯化碳样品的研究。结果表明。
The characterization of a simple, dual fiber optic sensor with a clear capillary has been studied. The Raman scatter signal of carbon tetrachloromethane with this capillary/fiber optical was acquired, From this spectra, the scatter signal intensity and the signal/noise ratio were enhanced about 20 fold. The Raman scatter signal was also obtained the with this kind of sensor by using different capillaries with different diameter and different sample length. The conclusion is the slimier capillary has the more enhancement than the big ones and the longer sample length has the stronger signal than the short ones.
