An optical strain gauge based on a balloon-like interferometer structure formed by a bent standard single-mode fiber combined with a 3D printer piece has been presented and demonstrated, which can be used to measure displacement. The interferometer h

In many areas, the analysis of a cylindrical structure is necessary, and a form to analyze it is by evaluating the diameter changes. Some areas can be cited: pipelines for oil or gas distribution and radial growth of trees whose diameter changes are

In this article, we proposed a simple optical sensor for flow measurement. The sensor structure is based on an in-line Mach–Zehnder interferometer formed by splicing an input single-mode fiber section and an output single-mode fiber section to a si

A method based on multiple Fiber Bragg Gratings (FBG) and a structure fabricated using a 3D printer for diameter measurement is proposed and experimentally demonstrated. The sensor is easily developed inserting the FBG on the structure and fixing the

Two Mach-Zehnder Interferometers based on Core Diameter Mismatch structures are proposed and experimentally investigated for curvature measurement. The sensing configuration consists of an input SMF, a section of SMF spliced between two MMFs and an o
