The structure and evolution of thermogravitational buoyant jets in a high-viscosity liquid above a linear source of heat suddenly switched on are studied by methods of the Hilbert optics and shear interferometry. Based on the interferogram structure, reconstruction of the temperature field in the jet is performed with using approximation by Bernstein polinomials and Bezier curves. Recovery the phase function and the temperature of the plume was carried out on the interferogram using spline interpolation. Reliability of the results was tested by simulating shear interferogram of the reconstructed field and comparing it with the experimentally obtained fringe pattern. Such jets can be considered as a model of an upward flow in the spreading zone in geodynamic problems associated with the behavior of the Earth's mantle at large depths.
