Abstract: In this work, we present a high-sensitivity fiber-optic temperature sensor based on the enhanced Vernier effect. The sensor consists of a cascade of three Fabry–Perot interferometers (FPIs), ...

Abstract: A highly sensitive fiber temperature sensor based on the Vernier-like effect and composite Fabry-Perot interferometers (FPIs) constructed with a photopolymer probe is proposed. The composite ...
