摘要:

本文发展一种利用物质的反常色散及相应的吸收峰组成光纤浓度传感系统。阐明其原理和测量方法 ,并讨论了对单组分、多组分以及有混浊干扰的液体所作的实验。结果说明此系统有较高的选择性

Abstract:

This paper develop a sensing system of density with optical fiber utilizing the anomalous dispersion and corresponding absorb peak of the matter.The principle and the method of measurement is introduced.The experiments on the measurement of single-solvent,multiple-solvent and single-solvent with muddy interference are discussed.The results showed that system has a quite good selectivity.
