Distributed and quasi-distributed fiber optic sensors are systems that connect opto-electronic interrogators to an optical fiber (or cable), converting the fiber to an array of distributed sensors. The
Learn all about the principles, structures, and features of eight sensor types according to their detection principles. The fiber optic sensor has an optical fiber
The light exits at the end of the fiber-optic cable and either hits an object which reflects it back (sensing/reflection principle) or it is detected directly by a receiver (through-beam principle).
As a sensing technology based on the principles of optical fiber, fiber optic sensors have gradually become key equipment in many industries due to
