本文介绍电扫描和光机扫描两种类型的扫描温度计.前者采用线性阵列电荷耦合器件作为光电探测器,微处理机作为信号处理器,应用于钢板、小目标等测温场合.后者由线性阵列发光二极管指示被测对象的温度分布,叠加在被测对象的可见光像上,用照相机实时拍摄记录,应用于能源管理,监测烟囱、窑壁、管道等的热泄漏状况. In this paper, two types of scanning thermometers, electric scanning and optical scanning, are introduced.The former uses linear array CCD as photodetector and microprocessor as signal processor, which is used in the temperature measurement of steel plate and small target.The latter consists of linear array LED indicates the temperature distribution of the measured object, superimposed on the visible light of the measured object, real-time recording with the camera records, used in energy management, monitoring the chimney, kiln wall, pipe and other heat leak conditions.
