Abstract

A real-time practical fiber micro-drop sensor, which can determine the physical and chemical parameters of the liquid, has been designed and realized. Liquid drops are formed at the tip of a liquid sensing head passing thin tubing. The infrared light is injected into the drop through an optical fiber and is received by another fiber after reflection, scattering and absorption with the liquid drop. The curve of the light intensity vs. time is called as Fiber Fingerprint Drop Trace (FFDT), which depends on the characteristics of the liquid to be tested. The trend and distinguishing feature of the FFDT is strongly relative to the shape-variation of the liquid drop. The correlation methods were induced to the signal analysis process.
