The paper presents the results of integrating of the fiber optic sensors (FOS) into the material of a metal-composite tank. It has been established, that FOS remain operable after all cycles of the technological processing. It was carry out technological development alternative technique for FOS location on end product and configuration output sensor on various segment of tank. It is shown that the integration of the FOS into the material of the structure makes it possible to analyze the changes of the structure deformations depending on the location of the FOS. Comparison of data display for FOS, located on outside surface and inside material of tank, to show possibility estimate evolution of defomation on time along depth tank. It was found that the readings of the FOS based on Rayleigh scattering and fiber-optic Bragg gratings (FBG) correlate well with each other, in case that the readings of the FOS are thermally compensated.

The article presents the results of work on the study of the dependence of the results of temperature measurements using fiber Bragg gratings (FBGs). It was found that FBGs not only have different initial sensitivity, but also exhibit nonlinearity even in a narrow temperature range (from –30 to +70 °C). It is shown that to use the FBG as temperature sensors, it is necessary to precalibrate the FBG by temperature.
