“…Then within the Iiniits of each step the value A (x,y) can be considered constant. In this case full change of contour length in result of object deformation can be presented AL = }dr = (4) where the curve r defmes a position of a step contour ( fig.lb) and simultaneously is a new integrating contour in (4), close to rectilinear. As is evident, the expression (4) coincides with Rahdon transform from function div A (x,y) .This function will be reconstructed by using of tomography methods realizing back Rahdon transform.…”

A problem of tomography reconstruction of vector physical fields by using the sets of a contour integrals from a vector projection and from projection of a vector derivative with respect to direction is investigated. A necessity of using nonrectilinear measuring lines for tomography reconstruction of vector field parameters distribution is shown. If the measuring line output signal is proportional to integral from projection of a researched vector it is possible to use the measuring line in form of a narrow loop and the decision of a problem can be received by using of integral theorems. If the measuring line output signal is proportional to integral from projection of a vector derivative with respect to direction (e.g. problem of deformed two-dimensional object), it is possible to use the measuring line of step form and potential component of a vector field can be reconstructed.The method can be widely applied to research a distributions of an electromagnetic, deforming and other vector fields inside elements of technical and technological objects constructions and also can to become a basis of systems of vector physical fields monitoring.

“…One of the most promising types of interferometers for creating interference fiber transducers is a single-fiber intermode interferometer [1] which operates on the principle of interference of the modes of the same fiber. Reports about a usage of the SFMI in the regime of the two modes excitation to measure the deformation of the technological elements verify the SFMI's ability to combine the simplicity of its optical scheme, a high sensitivity to deformation influences and a high temperature stability [2].…”

Possibilities of obtaining quantitative information about the deformation influence on the SFMI with a small number of excited modes by using a correlation method are investigated. It was shown that usage of diffusive scatterer allows us to transform the radiation of SFMI to a speckle field which can easily be processed. The working range of the SFMI deformation measurements is 0 – 160 µm with precision up to 10 µm.
