Abstract

A Fabry–Perot (FP) cavity, formed by a single-mode fiber (SMF) fusion spliced with a section of hollow fiber, was proposed and experimentally used as a sensor for liquid surface tension measurement. Due to the FP cavity length changing with different liquids, the surface tension can be measured by monitoring the interference wavelength spacing. In our experiment, five kinds of liquids were measured, and the relationship between wavelength spacing and liquid surface tension was obtained. The experimental results show that the achieved sensitivity to liquid surface tension is 30.96 nm/(N/m), and the maximum error is 5.43%.
