ADDRESSABLE FIBER BRAGG STRUCTURE WITH WAVE AND PHASE COMPONENTS AS A NEW TOOL OF MICROWAVE PHOTONIC TECHNOLOGIES
Abstract
The article presents the methods of analysis and principles of formation of addressable fiber Bragg structures with wave and phase components as a new tool of microwave photonic technologies and formulates the tasks for creation on their basis of microwave photonic quasi-distributed addressable sensor systems for monitoring and technical diagnostics of pipelines of power plants (an example of application). The necessity of synthesis of addressable fiber Bragg structures with wave and phase components is substantiated, their mathematical model is developed, the features of the main address of the structure and its additional addresses, which are key for processing optical information in the radio range, are determined. Based on the results of addressable fiber Bragg structures with wave and phase components optomechanics analysis, microwave photonic technologies of their interrogation and the structure of a microwave photonic quasi-distributed addressable sensor system for determining the temperature of a pipeline when sensors operate in reflection mode are proposed. Practical recommendations are given for recording the studied structures in fiber.
