Optical Fiber Based Temperature Sensors: A Review

Abstract

Current generation witnesses a huge interest in optical waveguide due to their salient feature such as low cost, immune to electromagnetic interference, easy to multiplex, compact size, etc. These features of the optical fibers makes it an useful tool for various sensing applications including medicine, automotive, biotechnology, food quality control, aerospace, physical and chemical monitoring etc. Among all the reported application, the device has been widely exploited to measure the physical and chemical variation in surrounding environment. Optical fiber based temperature sensor plays a crucial role in this decade to detect high fever and tackle COVID like pandemic. Recognizing the major developments in the field of the optical fibers, this article aims to provide recent progress in temperature sensor utilizing several sensing configuration including standard fiber, photonic crystal fiber, and Bragg grating fibers. Additionally, the article also highlights the advantages, limitations, and future possibilities in this area.

Secure IoT Routing through Manifold Criterion Trust Evaluation using Ant Colony Optimization

“…They acquire environmental data and perform real-time transmission over the hosted IoT network [1]. These compact electronic devices can sense various environmental attributes, such as chemical composition, motion, sound, light, pressure, humidity, and temperature, depending on their application or the environment in which they are deployed [2][3][4][5]. In the context of IoT, sensors acquire information from the physical world and forward it to a sink node for analysis [6].…”
