Working principle of fiber optic high-speed sensors
Here's how fiber optic sensors work: The system includes a light source, optical fiber, sensing element (or transducer), and a detector. It's a device that converts light rays into electronic signals. Think of it like a photoresistor, which changes its resistance based. However, sensors based on fiber‐optics have been developed rapidly because of their excellent sensing performances and capability to function in remote and harsh environments. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time.

How to solve interference in fiber optic sensors
Some noise sources can be reduced or eliminated by proper design, shielding, or isolation of the sensor system, while others may require more sophisticated signal processing techniques to filter out or compensate for the noise. These in-fiber interferometers make use of the sensitive phase variations of waves propagating in fibers to produce intensity variations, resulting in better sensitivities compared to many pure intensity-based sensors. This chapter addresses simple optical fiber sensors based on modal interference. We give a general model of F-P interferometric optical fiber sensors including diffraction loss caused by the beam divergence and the Gouy phase shift. They have many advantages over conventional sensors, but they also face some challenges.
