Fiber Optic Interferometric Temperature Sensing Characteristics

In this chapter, a temperature sensor is demonstrated based on four different techniques; intensity modulated fiber optic displacement sensor (FODS), lifetime measurements, microfiber loop resonator (MLR) and stimulated brillouin scattering. Fiber optic interferometers to sense various physical parameters including temperature, strain, pressure, and refractive index have been widely investigated. They can be categorized into four types: Fabry-Perot, Mach-Zehnder, Michelson, and Sagnac. This makes them suitable for use in space applications and hazardous environments such as high-voltage machinery (e., generators, motors, transformers), nuclear power. Fiber Bragg gratings are very efficient at temperature sensing and are easy to implement; however, they always need additional techniques to discriminate the Bragg shifts by temperature and by strain/compression and they also require expensive phase-masks.

Classification of Fiber Optic Sensing Sources

This article explores the different types of Fiber Optic Sensors, their working principles, and various applications. A sensor is a device that measures a physical quantity and converts it into a. 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. 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. However, the current literature contains. ibration and extreme heat etc. Due to its small size, low cost and ease of fabrication leading it to replace traditional sensors which were used frequently before th birth of fiber optic sensors.
