The aim of this work was to develop a method of panoramic optical diagnostics of the inhomogeneity of the density field in stratified flows based on the registration of the distribution of the Rayleigh scattering intensity using structured laser radiation. Several approaches have been implemented for organizing spatial modulation of laser illumination, intended for use with various values of the incident radiation energy density. To test the processing and reconstruction algorithms of the experimental data, a series of measurements was carried out using the method of planar laser-induced fluorescence. The distribution of local density in a jet of carbon dioxide flowing into atmospheric air was measured experimentally using a method based on the registration of Rayleigh scattering.
