Abstract

We evaluated the measuring capabilities of a high-resolution fiber-optic strain sensor based on a miniaturized Fabry-Perot interferometer (FPI). We designed an opto-mechanical setup to experimentally evaluate theoretical analyses and verify its reliability. High-resolutions are needed to testing performance of new designs. Sensors must not alter design intent and be immune to electromagnetic interference. After calibration, results indicate a gage factor on the order of 40mV/236229, proving the capabilities of the fiber FPI for high-resolution measurements of strain. The fiber FPI has been proven to provide high-resolution measurements in conditions where conventional strain sensors may fail to provide reliable results.
