Abstract

In this paper the possibility of pipeline diagnostics using the optical fiber grid spherical gauge is considered. Constructions of a fiber grid on the basis of multimode fibers and fiber Bragg gratings have been investigated. Breadboard models of different gauge constructions have been implemented and investigated. It has been established experimentally, that the gauge design based on the fiber Bragg gratings possesses higher sensitivity for deformation. However, the gauge based on the multimode fiber is more robust to the temperature influence.
