HIGHSPEED MONITORING OF EXTENDED OBJECTS USING FIBER-OPTICS SENSOR SYSTEMS BASED ON BRAGG GRATINGS
(pp. 4

Abstract. The need to use various methods of nondestructive testing and technical diagnostics for solving problems of monitoring technical complexes and systems is due to the increase in the number of their structural elements, the complexity of the functioning algorithms, and the aging of equipment in operation by their considerable extent. Large amounts of information obtained from various sensors of monitoring systems require significant computational resources for its rapid processing and generation of reports on the state of the system to assess its residual resource. The choice of the monitored parameters of the object is generally individual and can include a number of physical quantities. In this article, only temperature and deformation are affected. From the point of view of temperature control and deformation, there are several approaches: with the use of traditional sensors of piezoelectric sensors or fiber optic sensor systems. The analysis of control possibility with the help of optic sensor systems based on Bragg gratings was carried out. The article emphasizes high-speed (> 10 kHz) digital signal processing after optoelectronic transformation.

Keywords: interrogator, bragg sensor, fiberoptic systems, FPGA, centroid method, gauss approximation.
