摘　　要：本文介绍了一种利用遮蔽板作为标准噪声辐射源、以 80 31单片机为核心实现的实时在线测量静止及慢速运动的高温物体的比辐射率及温度的系统。系统由光学接收系统、信号放大与处理系统及显示系统组成。文中还介绍了该系统的原理与结构 ,讨论了其中的技术难点及其相应的解决方法 ,分析了系统工作波长的选择、扇形板关闭时的 P1 、开启时的 P2 及标准噪声辐射源的辐射能In this paper, the precise measurement instrument, which could simultaneously measure temperature and specific radiance of static or slow velocity high temperature object, is introduced. This instrument uses shelter plate as standard heat noise radiating source, and uses 8031 microcontroller as signal processing center. This instrument mainly consists of optical receiving system, signal amplifying and controlling system, and display system.Principle and structure of the instrument is presented. The key technologies and the corresponding solution methods are discussed. The effect on specific radiance and temperature measurement precision by choice of working wavelength, P 1 measurement accuracy while fan shaped plate is closed, P 2 measurement accuracy while fan shaped plate is opened and P 3 measurement accuracy are analyzed.
