Monitoring changes in water temperature and pressure at the seafloor can improve understanding of ocean circulation, climate, and natural hazards such as tsunamis. In recent years, scientists have ...

An ultra-short fiber Bragg grating (US-FBG) refractive index (RI) sensor is presented and demonstrated. The US-FBG is composed of a series of cascaded microchannels which carved by femtosecond (fs) ...

Temporal multiplexed fiber Bragg grating (FBG) sensing system for detecting physical parameters with a high spatial resolution is desirable for applications such as structure health monitoring, oil ...
