How does FOS work?

Sensuron’s FOS technology uses 200-micron diameter glass fibers that have been continuously inscribed with Fiber Bragg Gratings (FBG). FBGs are the unique optical sensing element that turns ordinary telecom grade optical fiber into a powerful and robust sensing tool. These sensors act as embedded mirrors inside the fiber that reflect a specific wavelength. When an FBG fiber is bonded to a material and interrogated with light, the FBGs will reflect different wavelengths as the fiber is strained. This enables real-time monitoring of applications for precise measurement and unparalled performance.
