为了同时探测混合溶液中多种溶质的浓度,提出一种用光纤法布里-珀罗谐振器作为传感器测量混合溶液中多溶质浓度的测量系统.从理论上分析了光纤法布里-珀罗谐振器干涉透射波长与混合溶液浓度之间的关系,采用光纤法布里-珀罗谐振器干涉透射波长实现了高准确度同时测量混合溶液中多溶质浓度的原理和可行性.构建了由InGaAs发光二极管光源、光纤耦合器、FFPR传感器、光电信号转换和放大器、光谱分析仪等组成的测量系统.对乙醇和甘油的9组标准混合溶液进行测量实验,并用测量结果标定了混合溶液中各溶质浓度与光纤法布里-珀罗谐振器传感器干涉透射波长之间的数学解析关系式.根据数学关系式用Action Script 2.0脚本语言编写程序,计算机实时监控了混合溶液中各溶质浓度的变化过程.

In order to simultaneously detect the multi-solute concentrations in mixed solution,system for measuring the multi-solute concentrations in mixed solution using optical Fiber Fabry-Perot Resonator(FFPR) is proposed.The relation between FFPR interference transmission wavelength and concentrations of the mixed solution is analyzed theoretically.The measuring system consists of an InGaAs LED,fiber coupler,FFPR sensor,opto-electrical convertor,amplifier and spectrometer.The analytical equation between concentrations and interference transmission wavelengths is standardized by measuring the samples contain ethanol and glycerin.The action script 2.0 is used as the programming language according to the mathematical relation.The real-time variation of the concentration change is monitored by the PC.
