Abstract

We propose a single-mode optical fiber sensor for characterization of physical and chemical properties of liquids. The sensor is based on monitoring changes in the back-reflected signal from the interface between the fiber end-face and the liquid sample. Changes in the reflection spectrum are registered while dipping the cleaved end of an optical fiber into liquid samples and different spectral variations are observed owing as a consequence of characteristic properties, such as surface tension, viscosity and refractive index, among others. We present results obtained for different liquids (distilled water, methanol, glycerin, silicone, mineral oil) showing the feasibility of this approach for developing a simple fiber optic liquid analyzer.
