摘要
文中介绍了一种利用钽酸锂热释电探测器作光电转换器件实现的实用化比色测温仪。该仪器由光学接收系统、信号放大与处理系统及显示系统三部分组成。介绍了该仪器的工作原理与结构,讨论了其中的技术难点及其相应的解决方法,分析了各量的测量精度对测温精度的影响。初步的实验结果表明,在待测温度高于400℃时,测温精度符合设计要求。
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℃.
