Fiber optic current sensor physical object
A fiber-optic current sensor (FOCS) is a device designed to measure direct current. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Fiber optic current sensors are revolutionizing the way electrical currents are measured, providing high sensitivity, immunity to electromagnetic interference (EMI), and the ability to function in harsh environments. Due to its small size, low cost and ease of fabrication leading it to replace traditional sensors which were used frequently before th birth of fiber optic sensors.
