A fiber-optic tomographic measuring network is proposed, in which quasi-distributed measuring lines are laid along curved trajectories (Fig. 1).

Fig. 1. Fiber-optic tomographic measuring network.

The measuring network presents a number of nonlinear measuring lines with fiber-optical amplitude sensing elements. The proposed topology of the measuring network makes it possible to significantly reduce the number of lines. The data processing is carried out by a neural network containing an inner layer of nonlinear neurons. The results of numerical experiments, as well as experiments with the layout of a measuring network of dimension 8^8, are presented (Fig. 2).
