Fiber optic sensors operate by transmitting light through an optical fiber, where environmental changes affect the light's properties. These changes are captured as control signals that represent the measured physical quantity, such as temperature, pressure, strain, or displacement . The basic system includes a light source, optical fiber, sensing element (transducer), and a detector. The transducer modulates the light in response to the measurand, and the detector converts the modulated light into an electronic signal for analysis .
Fiber optic sensors generate control signals through several modulation methods:
The modulated light is converted into an electronic signal using photodetectors or optical receivers. These signals can then be processed for real-time monitoring, feedback control, or safety interlocks. For example, in industrial applications, fiber optic sensors can trigger alarms or control actuators when strain, temperature, or pressure exceeds predefined thresholds . Multiplexing techniques, such as wavelength division multiplexing, allow multiple sensors to share a single fiber, each producing distinct control signals .
As a sensing technology based on the principles of optical fiber, fiber optic sensors have gradually become key

A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing. Depending on the application, fiber may be used because of its small size, or because no electrical power is needed at the remote location, or because many sensors can be multiplexed along the length of a fiber by using light wavelength shift for
