In the Optica Publishing Group journal Applied Optics, the researchers describe their new sensor, which uses an optical fiber and an optical phenomenon known as localized surface plasmon resonance.

“This solution allows us to utilize our current fiber optic network in a new way to increase resilience in areas of northern and central Minnesota.” Instead of installing physical sensors on ...

Fiber-optic sensors have several drawbacks ... We used the voltage readings from the electrodes as input vectors in the ...
