  • What is the working principle of a perimeter fiber optic sensor

    What is the working principle of a perimeter fiber optic sensor

    It works on the principle that any physical perturbation—whether caused by an intruder, animals, or environmental factors—will affect the light signal within the fiber, triggering an alert. One of the primary advantages of fiber optic perimeter sensor systems is their unmatched. Fiber optic sensors, known for detecting minute disturbances, offering long-range capabilities, and resisting electromagnetic interference, play a key role in modern perimeter security. This article explores how fiber optic sensors work in PIDS, their types, and their contribution to enhancing. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. It's a device that converts light rays into electronic signals. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy.
