1. Light Source: Fiber optic sensors use light sources such as laser diodes, LEDs, or superluminescent sources to generate the optical signal that travels through the fiber. The choice of source depends on the required precision, wavelength, and application environment . 2. Optical Fiber: The optical fiber acts as the medium for transmitting light. Fibers can be plastic (lightweight, flexible, cost-effective) or glass (high-temperature tolerance, precise measurements). The fiber consists of a core and cladding, which guide light through total internal reflection . Fibers can be configured in thru-beam (separate transmitter and receiver) or reflective (single unit) arrangements . 3. Sensing Element (Transducer): The transducer modulates the light signal in response to a physical quantity such as temperature, pressure, strain, or displacement. In intrinsic sensors, the fiber itself acts as the sensing element, while in extrinsic sensors, the transducer is external, and the fiber only transmits light to and from the sensor . 4. Detector: The detector receives the modulated light and converts it into an electrical signal. This can be a photodiode or other light-sensitive device that measures changes in intensity, phase, wavelength, or polarization . 5. Electronic Processing Unit: The electronic processing unit analyzes the signal from the detector. Devices such as wave analyzers, optical spectrum analyzers, or oscilloscopes are used to interpret the changes in the optical signal and quantify the measured physical parameter .
