The monitoring principle of fiber optic sensors is
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. Think of it like a photoresistor, which changes its resistance based. Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity, electromagnetic interference (EMI) immunity, and long-term stability. The basic working principle is that when the light signal passes through the optical fiber, parameters such as light intensity, wavelength, and phase will be affected by the. The fiber optic sensor has an optical fiber connected to a light source to allow for detection in tight spaces or where a small profile is beneficial. The optical fiber consists of the core and the cladding, which have different refractive indexes.
