Chemosensitive fiber optic sensors are a new class of devices that are beginning to emerge and find more and more applications in many fields. Current advances in optoelectronics, fiber optics and spectroscopy have added new dimensions to the use of chemical and biochemical sensors. The main advantages of optical fiber sensors over other common sensors include low cost, ruggedness, flexibility and ease of miniaturization. In addition, these sensors do not require separate reference devices, this reference can also be used optical method. Devices are immune to electrical interference, safe and efficient, and operate remotely, even in harsh environments. Fiber optic chemical sensors combine the advantages of optical fibers with the chemical and biochemical properties of the analyte. This technique is right
