Abstract
Diffusion burning of a hydrogen jet is studied by methods of the Hilbert optics. A diagnostic system based on the batch-produced IAB-463M device is implemented, which includes a specially developed Hilbert filtration module coupled with a light source. The influence of local turbulent perturbations (puff or slug) arising in the tube forming the jet on the dynamic structure and flame evolution is revealed. This phenomenon can be used to control the space-time structure of the flame
