Abstract
A new thermal expansion sensor is presented in this letter. It combines an interferometric fiber sensor and an erbium-doped fiber ring laser as the light source. The sensor consists of a combination of single-mode, hollow-core, and no-core mirror fibers. The sensor was tested on two different types of based metal, such as aluminum and steel, giving sensitivities as high as 38.7 and 5.75 nm/°C, respectively, showing good performance.
