MEASUREMENT OF ULTRAFAST CHANGING TEMPERATURE USING OPTIC FIBER NON-CONTACT METHOD

Abstract

Due to their unique properties, optical fibers are used in wide branches, including medicine, the motor industry, aircraft, mechanical engineering, telecommunication, Internet networks and etc. Optical fibers differ from traditional cables with their high bandwidth, immunity to electromagnetic influence. The application of optical fiber not only for the transfer of information but also for sensor technologies is an important problem from a technical point of view. The problem becomes more interesting in such applications where traditional sensors are not able to detect transient processes. Among these problems, the fast change of temperature of an object in the industry can be solved using optical fibers.

By means of the present article, I propose a possibility of application of optical fibers in industry, in particular, for fast and continuous measurement of temperature. The properties of present optical fibers and suggestions of using them in hightemperature environment are discussed.
