Hilbert-Optic Diagnostics of Hydrogen-Oxygen Inverse Diffusion Flame

The aim of this work is to adapt the methods optical Hilbert diagnostics for visualization and study inverse diffusion H2/O2 flame. diagnostic complex implemented on basis IAB-451 device with modified filtering. Visualization phase perturbations induced by studied medium in a probing multiwave light field performed via polychromatic Foucault-Hilbert transformations combination registration RGB-per-pixel processing dynamic structure images. From solution problem optics using physically justified initial approximation under consideration, temperature flame reconstructed value H2, H2O, O2 N2 concentrations may be restored.
