- Abstract
Methods of recording and automated processing of the results of phase-modulated speckle interferometry of optically dense (opaque to intrinsic radiation) flames containing a condensed phase are described. The use of a high-speed single-frame measurement technique and special processing procedures made it possible to determine the spatiotemporal distribution of the refractive index, based on which the flame structure can be identified. As an example, the results of a study of the burning torch of a stationary droplet of medical paraffin are presented.
