摘要
On the basis of thermal radiation from solid surface to measeure tem-perature,a new two-color optical fiber pyrometer is put forward.It gets two thermal radiation signals by the method of Y-type optical fiber and narrow band filter for indi-cation of the temperature,Si diode in used for photoelectric measurement and MCS-51 single-chip microcomputer for sampling and handling.The system can output in digital and can print out instantaneous value,peak value and valley,It has many advan-tages such as quick measurement,small objective,high precision,high sensitivity and non-emissivity compensation.in addition,the special circuit of this pyrometer and the es-tablishment of mathematics model are discussed.
