利用长周期光纤光栅测量蔗糖溶液浓度的仿真研究

Simulation Research on Measuring the Concentration of Sucrose Solution by Using Long Period Fiber Grating

通过对长周期光纤光栅测量蔗糖溶液浓度的仿真研究,发现长周期光纤光栅谐振波长与10%到75%的蔗糖溶液浓度呈非线性关系,在70%处灵敏度较高,进一步研究发现在20%处呈现线性关系,但灵敏度较70%处低。

This paper makes simulation research on measuring the concentration of sucrose solution by using long period fiber grating. The result shows that the relationship between the syntony wavelength in the long period fiber grating and the concentration of sucrose solution from 10% to 75% is nonlinear, and the sensitivity is high when the solution concentration is 70%. Further research shows that the relationship is linear when the concentration is 20%, but the sensitivity is lower.
