The principles of visualization and measurement of surface temperatures and heat fluxes by the method of liquid-crystal tomography in an aerophysical experiment are described. The properties of polymeric liquid-crystal, heat-sensitive coatings and application of them in subsonic and hypersonic facilities for investigating the structure of a near-wall flow and aerodynamic heating are considered.
