A method for measuring the temperature fields on the surface of an object under study using luminescent temperature transducers (LHT), comprising applying a thin coating layer luminescent on the surface to be studied under illumination by exciting radiation, the luminescence intensity of which depends on temperature, characterized in that the coating is based on a polymer having nitrol varnish or polyurethane varnish, uniformly mixed under normal conditions with two phosphors: active against temperature with rhodamine and a reference pigment, which is insensitive to temperature, while the pigment mixed with varnish and rhodamine do not interact with each other and luminesce in different spectral regions, which allows one to obtain the desired temperature distribution on the surface of the object under study by digitally processing two images simultaneously recorded in spectral intervals corresponding to the luminescence of rhodamine and pigment.
