Polychromatic hilbert-diagnostics of evolution of the ring whirlwinds arising at diffraction of front of pressure upon the aperture

Formation and distribution evolution gas-dynamic the toroidal vortical structures in pairs arising and extending in opposite directions at various values of pressure in the gas chamber is considered. In work the color gilbert-filtration of not coherent optical field revolted with investigated vortical structure was applied to registration of whirlwinds inside and outside of the chamber. The color gilbert-visual analyzer phase objects in real time on the basis of the shadow device with the polychromatic slot-hole light source coordinated with the phase filter, and the digital camera operated by means of the computer was used.
