Abstract

The aim of this work is to adapt the methods of optical Hilbert diagnostics for the visualization and study of inverse diffusion H 2 /O 2 flame. The diagnostic complex is implemented on the basis of the IAB-451 device with modified optical filtering. Visualization of phase perturbations induced by the studied medium in a probing multiwave light field is performed via polychromatic Hilbert and Foucault-Hilbert transformations in combination with registration and RGB-per-pixel processing of the dynamic structure of the images. From solution to the inverse problem of Hilbert optics using a physically justified initial approximation of the problem under consideration, the temperature field of the flame is reconstructed and the value of the H 2 , H 2 O, O 2 and N 2 concentrations may be restored.
