Abstract
In this work the conception of the fiber Bragg grating (FBG) application in the capacity of the temperature distribution sensor, on the grating length, is presented. In the method of temperature distribution measurement, by using of FBG element, the key issue is an estimation of the grating periods distribution (and connected with this estimation - temperature distribution) from measured grating transmission spectrum (an inverse problem). The article presents measurements results used for evaluation of selected methods for solving an inverse problem, which can be used in temperature distribution recovery from FBG spectrum. We have also presented utility evaluation results of the selected methods for numerical solution of the inverse problem for temperature distribution recovery.
