利用红外热像仪进行物体表面波段法向发射率测量
Surface Band Normal Emissivity Measurement Using Infrared Thermal Imager
摘要
Abstract
The radiation thermometry is widely used because of fast response and wide range of temperature meas-urement,and emissivity is the main parameter that affects the accuracy of radiation thermometry. The emissivity of different objects and same object with different surface temperatures and conditions is different in fact. In order to obtain the surface band normal emissivity of the object and improve the accuracy,infrared thermal imager is used. The temperature measurement principle of infrared thermal imager was introduced,and then the emissivity measure-ment method was proposed. In view of different detectors,working bands and temperature measurement ranges of in-frared thermal imager,the n values are different in emissivity calculation formula. n values for the applied infrared thermal imager in different temperature ranges were calculated. The infrared thermal imager and the colorimetric py-rometer were used to measure the surface band normal emissivity of the high temperature ceramics,and the result was verified. Experimental results show that the band normal emissivity measured by this method is reliable,and the temperature measurement error is less than 1% after correction.关键词
