An overview of optical fiber sensing techniques for various applications

In this research he sheds light on sensor technologies, especially those that used optical fibers of all kinds as a sensor. The most important applications used in the field of optical pulp sensitization are reviewed, in addition to the development in recent years of PCF sensors. In this way, the use of optical fibers as a sensor is reviewed in several areas, including measuring and monitoring environmental pollution, gas leakage sensor, refractive index sensor, and sensors in several other areas. Their presented results, in order to reach previously published best results in the use of PCF for optical, biological, and chemical sensors.
