A Practical Real-time Colorimeter Using Pyroelectric Detector
LIU Xinjian(Department of Physics,Xinyang Teachgers'College,Xinyang 464000,China)
A new kind of the practical IR colorimeter using LiTaO3 pyroelectric detector is presented.This instrument consists of three parts:optical receiving system,signal amplifying and controlling system,and display system. The principle and the structure of the instrument are introduced.The key technologies and the corresponding solution methods are discussed.The effects on temperature measurement precision and the corresponding solution methods are discussed.The effects on temperature measurement precision of Pλ1 and Pλ2 are analyzed.And some experimental results show that temperature measurement accuracy is suitable for our requirement at higher than 400℃.
