Abstract
The paper formulates general requirements for the formation of spatial topologies of quasi-distributed fiber-optic systems of embedded monitoring based on fiber Bragg gratings for monolithic and three-layer structures made of polymer composite materials. The main types of spatial topologies of fiber-optic sensors for the implementation of an effective quasi-distributed system of embedded diagnostics of composite structures are considered. The main methods for interrogating arrays of fiber-optic sensors that form a quasi-distributed system of embedded diagnostics of composite structures are analyzed, an overview and analysis of the technical characteristics of foreign and domestic interrogation equipment is given. It has been established that for practical applications, taking into account the relative simplicity of physical implementation and the availability of interrogation equipment, it is advisable to use a mixed topology of fiber-optic sensors, which includes elements of serial and star topologies, with he spectral channel separation method being the most optimal.
