A dual-FBG and F-P cavity compound optical fiber sensor based on a multi-core fiber (MCF) is proposed. A hollow core fiber (HCF) was fused between a single-mode fiber (SMF) and a MCF to form the F-P ...

This article presents the development and experimental verification of a temperature and humidity sensor featuring a stable structure and high sensitivity. The sensor utilizes a Mach-Zehnder ...
