The goal of the work is the synthesis of light fields with a series of optical vortices that do not enter topological reactions between them and have linear and nonlinear skeletons. Conduct theoretical and experimental studies on the study of singular skeletons and conduct a comparative analysis of the results. In the process of work, based on the theory of diffraction, calculated singular skeletons that arise when passing a Gaussian beam through a double phase wedge. Their trajectory and internal structure of the optical vortex core are determined. Conducted joint experimental research at the University of Wroclaw for the registration of a singular skeleton with the help of the spatial modulator of light and interference schemes. A comparative analysis of the obtained data with theoretical results is carried out; the relative deviation in the determination of the coordinates and parameters of the core of the optical vortex is up to 5%. The use of diffraction lattice with bifurcation of a stroke as a beam separator in interference schemes is proposed, its advantages and additional possibilities are demonstrated in comparison with traditional methods. The creation of optical information system, which uses diffraction and interference intensity distributions as data, has been started and provides analysis and comparison of coordinates of topological objects.
