应用光纤液滴传感器进行液体测试

Liquid testing using fiber drop sensors

光纤液滴传感器是利用测试液滴的形成过程与液体成份之间的关系而制成的一种液体测试传感器。主要利用光纤来监测液滴的增长过程,得到随液滴下降过程的光强变化情况,从中获得反映液体的物理、化学性质的“液滴指纹图”。通过对指纹图进行分析对比得到液体的特性参数,实现对各种液体的鉴别。

The optical fiber drop sensor is a type of the liquid-testing sensors based on the relationship between the dripping process and the characters of the liquid to be tested.The fiber drop sensor can be used to monitor the variety of the light intensity relative to the dripping process of the liquid drop.The fingerprint drop trace,which indicates the physical and chemical properties of the liquid,can be obtained and used to discriminate different kinds of liquids.
