“…However, there are certain objects which are dispersive or nontransparent for penetrating radiation. In this case it can be rather difficult to use such methods so we can substitute extensive fiberoptical measuring lines with integral sensitivity [2] for light beams which contain the information about antiderivatives of field distribution function. Such substitution gives us a new opportunity for tomographic studies which concerned with higher noise immunity and measurements precision.…”

The possibilities of the development of the 1-D tomographic fiber-optical measuring system based upon the set of the loop-shaped fiber-optical measuring lines with different lengths were investigated. Single fiber multimode interferometers were proposed as measuring lines. The system's signals processing algorithm was developed. The scheme of the arrangement of the single fiber multimode interferometers in the 1-D multichannel tomographic system was offered. The reconstruction of the lateral deformation pattern in the object (structural beam) under study was shown.
