The paper reviews the latest results on the application of hyperspectral imaging spectroscopy to measure the temperature distribution and the emissivity on the surface of solids under high pressure and temperature in DAC In 2016, it was proposed to use a tunable acousto-optic imaging filter to measure the two-dimensional distribution of the temperature. Proposed method allows determining the distribution of the temperature by a large set of experimental points on the Planck curve, which leads to a high accuracy of temperature determination. An acousto-optic imaging filter as well as makes it possible to visualize an infrared laser radiation, to study the processes of melting and to measure the thermal conductivity of metals at high pressures and temperatures.
