Paper Abstract

The high temperature and its distribution are measured by using a CCD camera as a detector based on two-color thermometer technique and image processing technique. The rotary frequency of the filters located on a motor is synchronized with the vertical frequency of the camera. The camera receives the energy emitted from the object at wavelength (lambda) 1 and (lambda) 2. Through an A/D converter, the video signal is digitalized into 8 bit. After processing by operational circuit and a pseudo color processing unit, the digital signals are converted into three channels standard video signals. By inputing those signals into a color monitor, the temperature distribution can be displayed.
