Paper Abstract

The paper presents an algorithm for analysis of the fringe interferogram, registered by the matrix CCD-camera. It is new version of classical method of extremal lines. After an interferogram preprocessing, the set of reference section of interferogram is processed to find of coordinates of extremal points of interference fringes. Then, beginning at these points, along each of fringes, extremal lines are traced. Direction of each extremal line is corrected using of correlation comparison of local sample of the interference fringe with adaptive adjusting model of this fringe during tracing. Coordinates of extremal lines serves nodes of interpolation of the phase for building of the phase surface within the whole aperture where interferogram is given.
