A fiber optic sensor is a type of sensor that uses the optical fiber itself as a means of transmitting the signal from the remote sensor to the electronics that process the signals. A sensor based on ...

Optical fiber interferometric sensors are of great importance in chemistry, biology, and medicine disciplines owing to high-sensitivity and high-quality factor. However, due to the limitation of free ...

Brillouin scattering is the phenomenon of the inelastic scattering of light by thermally generated acoustic vibrations. Brillouin-based optical fiber sensing can be used to measure temperature and ...

Pipeline contents are typically valuable, volatile, and harmful to the environment if allowed to escape. With them being susceptible to aging, accidental damage, or tampering, the chances of an escape ...

Fiber-optic spectroscopy leverages light-guiding technology for remote sensing, offering a robust solution for real-time data ...

Fiber optics are a means of transmitting information at incredibly high speeds; however, the technology can be used for more than just providing a fast internet connection. Researchers reporting in ...

Researchers demonstrate that operating at modulation frequencies close to Brillouin bandwidth and suppressing signal distortions allows BOCDR to achieve a world-record spatial resolution of 6 mm.

The Wildfire season has changed. Once most active between the months of April through September, wildfires are now a threat year-round in the US. The fires are generally getting worse, too. According ...

The recent development in the utilization of flexible optical fiber sensors and the prospective application scenarios were then summarized, which encompass human activity monitoring and healthcare, ...

A project at Caltech has developed a fiber optic-based method to measure soil moisture in the shallow subterranean region between the surface and underground aquifers. Reported in Nature ...

A 100-year-old equation and a fiber-optic cable off the coast of Svalbard led researchers to discover they could detect swimming whales—even if they were completely silent. The discovery broadens the ...

Fight Fire with Light: Fiber optic networks power the overwhelming majority of global internet traffic at any given moment. They can also be used to develop extremely precise light-based sensors, ...
