Highly Sensitive Temperature Sensor Based on a UV Glue-Filled Fabry–Perot Interferometer Utilizing the Vernier Effect

A parallel Fabry–Perot interferometer (FPI) optical fiber sensor, enhanced with UV glue, was proposed for environmental temperature detection. The UV glue is applied to the fiber’s sensing region using a coating method, forming an FP cavity through misalignment welding, allowing the FP to function a...
