Popis:	The carried out researches allowed to motivate and put into practice the polarizatoin-optical method of temperature measurement based on the phenomenon of temperature alteration in value of birefringence of the optically anisotropic crystals. The practical realization of the method with the use of Al2O3 and LiNbO3 plates as active elements of thermometers has shown, that the application of Al2O3 is more preferable due to a wide temperature interval of employment of material, its mechanical and chemical stability, absence of phase transitions. LiNbO3 has such lacks as nonlinearity of graduate dependence and presence of a phase transition point. Nevertheless, its use allows to raise the sensitivity of the thermometer and to increase the accuracy of measurements.
