Highly Sensitive Gas Pressure Sensor Based on Fabry-Perot Interferometers and the Vernier Effect

A highly sensitive gas pressure sensor based on the Vernier effect (VE) and Fabry-Perot interferometers (FPIs) has been proposed. The sensing structure was fabricated by fusion-splicing a single-mode fiber (SMF) with two quartz-capillary sections of different inner diameters, followed by coating a polydimethylsiloxane...
