Development of Fiber-Optic Sensors System, Based on Fiber Bragg Gratings

An article herein considers the development of fiber-optic sensors system, based on fiber Bragg gratings. Presently, fiber-optic sensor has become world-widely known amongst sensor technologies, which is used for monitoring engineering and construction structures. The work is linked with developing the system from fiber-optic sensors on the basis of fiber optic gratings, its characteristics, deformation behavior and temperature, acting at fiber Bragg grating by means of computer modeling. The research is focused at analysis of characteristics and deformation and temperature behavior of fiber-optic Bragg sensor. Fiber-optic Bragg sensor with tilted grating is used for measuring deformation of the object, the strength of which is changed, dependent on the applied force, as well, for measuring and detecting any temperature deviations, influencing at fiber Bragg grating, which might bring to fire and accidents. In the research there was made simulation modeling in MATLAB(Simulink) software.
