一种物体比辐射率的新型四次测量法及增温补偿
A new method on estimating object emissivity by using four times measuring and principle of temperature compensation
摘要
Abstract
A "two times thermal irradiance and four times measuring method" was proposed to measure the surface emissivity of any object.Compared with the previous methods,the proposed method can completely eliminate the interference of the lens and cavity walls of the sensor to measure accurately the irradiance of the observed object,implying its ability to improve the accuracy of surface emissivity measurement and making the equipment of emissivity measurement portable.The designed 1 000 + w/m2 strong heat radiation source considerably improved the signal to noise ratio of the equipment.To compensate the wanning effect of the measured object under the strong heat radiation source,we proposed a universal expression to solve the emissivity in the non-isothermal system and a "Process Method" to reduce warming.The comparison of three measurement results showed that the proposed method outperformed the others.关键词
