Each hair-thin glass fiber in a buried fiber optic cable contains tiny internal flaws -- and that's a good thing for scientists looking for new ways to collect seismic data in places from a busy urban ...

The team describes their all-optical approach in a paper published today in The Optical Society's (OSA) journal Optics Letters. They successfully demonstrated simultaneous flow/temperature sensors at ...

Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound.
