Fabrication and sensing characteristics of a fiber-optic air pressure sensor based on the Vernier effect
A high-sensitivity fiber-optic pressure sensor is demonstrated, based on the Vernier effect in a cascaded dual Fabry–Pérot interferometer. The sensor incorporates a 343 μm polarization-maintaining fiber and a single-mode fiber, precisely aligned and secured within a ceramic sleeve to form an air cavity. The Vernier eff...
