摘要
On the basis of thermal radiation from solid surface to measure temperature,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 indication of the temperature,Si diode is 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 value,It has many advantages such as quick measurement,small objective,high precision,high sensitivity and non-emissivity compensation.In addition,the special circuit of this pyrometer and the establishment of mathematics model are discussed.
