Abstract
A laboratory prototype of a complex for high-speed visual-optical diagnostics of plasma-chemical synthesis in powder mixtures is described. The processes are initiated by microwave radiation of a gyrotron. The laboratory prototype allows imaging processes in the reactor and spectra of the resulting radiation. The prototype includes video cameras, spectrometers, and a synchronization system and suggests a possibility of installing an active filtration system based on metal vapor active media. The resulted images of the process of synthesis of various ceramic micro- and nanoparticles are presented. It is shown that the use of temporal filtering of optical images does not completely suppress the background radiation impact.
