The examples include intensity-based sensors or microbend sensor and evanescent wave sensor. What is a Fiber Optic Sensor? A fiber optic sensor measures a physical quantity by modulating the intensity. 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. Fiber-optic sensors (also called optical fiber sensors) are fiber -based optical sensors for some quantity, typically temperature or mechanical strain, but sometimes also displacements, vibrations, pressure, acceleration, rotations (measured with optical gyroscopes based on the Sagnac effect), or.
