Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

A review of the salinity measurement technology based on the optical fiber sensor is
presented. The principles of optical fiber measurement, the structures of probes and the …

Fiber Bragg Gratings (FBGs) are one of the most popular technology within fiber-optic
sensors, and they allow the measurement of mechanical, thermal, and physical parameters …

Current cell performance monitoring, which relies on measurements of sporadic surface
temperature through the battery management system (BMS), does not provide a reliable …

In marine environment, concrete structures can corrode because of the PH alkalinity of
concrete paste; and the salinity PH is heavily related with the concentration of salt in …

In this work, we have demonstrated a cladless few-mode fiber grating sensor for
simultaneous measurement of refractive index (RI) and temperature. The proposed sensor is …

A compact and high sensitivity sensor with a fiber-tip structure is proposed and
demonstrated for simultaneously liquid refractive index (RI) and temperature sensing. The …

A compact and simple fiber in-line modal interferometer with an embedded fiber Bragg
grating (FBG) is proposed and experimentally demonstrated for simultaneous measurement …

Due to the advantages of small size, high sensitivity, and strong anti-interference ability,
optical fiber sensors are widely used in gas detection. Meanwhile, concentration and …

In this paper, an integrated all-fiber Fabry–Pérot interferometer (FPI) sensor is proposed and
