Correlation analysis of the digital flow images with super- resolution

Original specklegram processing algorithms based on statistical analysis of digitally recorded speckle fields have been represented for quantitative diagnostics of the shock wave flow microstructure with the sub-pixel accuracy. Software developed allows to reconstruct about 10 000 vectors of the volume deformation of the speckle fields for area of 20×30 mm with magnification M = 1.
