宽动态测量范围的光纤液体浓度传感器

Optical Fiber Sensor of Liquid Concentration With Wide Dynamic Measuring Range

液体浓度变化引起折射率变化,利用测量光学材料折射率的V型棱镜法原理,可在较宽的动态范围内测量液体的浓度。

The variance of liquid concentration causes the variance of itsrefractive index. Liquid concentration can be measured in wide dynamicalrange according to the V-prism principle which is used to measure theoptical material refractive index.
