QUASI-DISTRIBUTED FIBER-OPTIC SENSOR NETWORK FOR DISTRIBUTION CONTROL EMF INTENSITY AND TEMPERATURE IN A CLOSED WORKING MICROWAVE CHAMBER MODERNIZED CALORIMETRIC METHOD

Abstract

 The article presents a comparative analysis of various technologies for measuring the distribution of electromagnetic field (EMF) intensity (at the stage of designing closed working microwave chambers) and temperature (at the stage of monitoring the implementation of thermal microwave processing of material media) when implementing a modernized calorimetric method using as temperature sensor of fiber Bragg structures in their different variations, which is determined both by the specific formulation of the problem of a scientific experiment on microwave processing of material media, and by the requirements for temperature measurement accuracy, cost and operational parameters of its implementation. For this purpose, the article includes an in-depth analysis of fiber Bragg structures in order to fully evaluate the most informational topology of their inclusion and search for the most accurate, fast and cheap interrogator for their interrogation. In conclusion, an analysis is made of the applicability of the considered options for solving various problems of monitoring microwave processes of heat treatment of material media and building closed working chambers for them.
