Wide Temperature Range Fiber Optic Sensor

Abstract

Currently, fiber Bragg gratings are the main type of sensor structure in fiber optic sensors. However, during their creation the protective-strength coating is removed, which reduces the strength and flexibility of the fiber and limits the field of application of such sensors. A solution to this problem could be the creation of a fiber-optic sensor using a new technology in which the protective-strength coating is not damaged, and the sensor structure is created using a fusion effect. When recording the sensor structure in a given area of the fiber, the conditions for generating a plasma focus are created, after the passage of which a structure of microneedles of various shapes is formed. Sensors created using such technology can operate in a wide temperature range. The aim of the present study is to determine the dependence of changes in the spectral characteristics of the sensor in the temperature range from 4 to 700 K.
