Abstract
The new method of quick temperature surface distribution measurement based on eight-colour video camera is presented. Measurement frequency is 80 Hz. The mathematical apparatus is developed for determination of temperature distribution in the camera field of view without using radiation capacity data. Statistical temperature measurement error is 10 % at 1170 K and 3 % at 1500 K. It is demonstrated that the multi-spectral measurement method is viable and allows us to obtain temperature distributions of objects with unknown composition.
