Over the last three decades, fiber optic sensors (FOS) have gained a lot of attention for their
wide range of monitoring applications across many industries, including aerospace …

Carbon dioxide (CO 2) is a colorless and odorless gas. The imbalanced CO 2
concentrations can have detrimental effects, therefore numerous CO 2 gas sensors have …

A fiber Bragg grating (FBG) and distributed Bragg reflection (DBR) fiber laser sensor
combined digital sensing system for both vibration and temperature sensing is proposed. To …

A vibration fiber sensor based on a fiber ring cavity laser and an interferometer based single-
mode-multimode-single-mode (SMS) fiber structure is proposed and experimentally …

A multi-longitudinal mode (MLM) laser beat-frequency optical fiber vibration sensor using a
frequency modulation (FM) radio integrated circuit module as the FM demodulation scheme …

It is found that the nonlinear dispersion of optical materials can induce the interference fringe
of phase-compensated wavefront splitting Mach–Zehnder interferometer (MZI) to split at a …

We demonstrate a highly sensitive fiber gas sensor with Vernier effect utilizing a reference
Sagnac interferometer (R-SI) in series with a sensing Fabry-Perot interferometer (S-FPI) for …
