What is the role of photoelectric and optical fibers in sensors
Photoelectric sensors typically convert light to electrical signals using semiconductor devices, while fiber optic sensors use the transmission properties of optical fibers to carry signals for measurement, giving higher sensitivity and wider measurement range. Fiber optic sensors are devices that transform the state of an object being measured into a detectable optical signal. Both use light for sensing, but their principles differ.

Fiber optic sensors transmit light based on their principle
Fiber optic current sensors work by detecting changes in light as it interacts with a magnetic field created by an electrical current. 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. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. Think of it like a photoresistor, which changes its resistance based. 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.
