| Abstract: | In this paper, the precise measurement instrument, which could simultaneously measure temperature and specific radiance of static or slow velocity high temperature object, is introduced. This instrument uses shelter plate as standard heat noise radiating source, and uses 8031 microcontroller as signal processing center. This instrument mainly consists of optical receiving system, signal amplifying and controlling system, and display system.Principle and structure of the instrument is presented. The key technologies and the corresponding solution methods are discussed. The effect on specific radiance and temperature measurement precision by choice of working wavelength, P 1 measurement accuracy while fan shaped plate is closed, P 2 measurement accuracy while fan shaped plate is opened and P 3 measurement accuracy are analyzed. |
