In the present paper the modification of the method of temperature measurements on the basis of infrared (IR) radiation detection is presented. The modification was carried out in order to satisfy the conditions of the dynamic shear with strain rate about 5 . 103 s-1. Owing to stopping the horizontal prism in the scanning system of the IR Camera, the frequency of a line of thermovision image has been reached 1.6 kHz. The theoretical ground of calibration procedure of the temperature rneasurement system is given.
