| Abstract: | A new kind of intelligent specific radiance on-line measuring instrument using laser is presented in this paper. The instrument consists of three parts:optical emitting and receiving system,signal amplifying and controlling system,and display system. In details,the optical emitting and receiving system is mainly composed of laser,chopper,collimator lens,extender lens,beam splitting mirror,filter module,focusing lens and pin photodiode. The signal amplifying and controlling system is mainly composed of signal amplifier,A/D converter and 8031 chip processor. And the display system is mainly composed of indicator,printer and I/O circuit. The key technologies,the corresponding solution methods and the effect on temperature measurement precision are discussed. |
