Abstract

Fundamental properties of the high speed video camera system were evaluated for the application of temperature measurement of molten particles by means of double wavelength pyrometric method. Results obtained were (1) the available resolution of this camera system is about 128 lines in a frame to get exact shapes of the objects and about 85 lines to get exact intensities of each object, (2) the intensity of each pixel can be graduated into 20 divisions. That is, it can be measured the accuracy of 50 degrees in the temperature range from 2000 to 3000 K. These results show that the camera system can be applied to the field of material processing.
