Single-mode fiber optic humidity sensor

The sensor consists of a symmetrical, non-adiabatic, tapered, single-mode optical fiber, operating at the wavelength near the dispersion turning point, and a cascaded fiber Bragg grating (FBG) for temperature compensation. We demonstrate an all-fiber, high-sensitivity, dual-parameter sensor for humidity and temperature. The evolution of optical structures developed towards humidity. A new optical fiber humidity sensor with high sensitivity is reported. By depositing a humidity sensitive material, such as poly (ethylene oxide) (PEO) on the bare SCSMF fiber, the proposed structure can act as. The Fabry–Pérot interferometer (FPI) structure has been designed and fabricated through the heterogene...
