Method for Measuring Object Surface Emissivity

According to measuring result of the atmosphere parameters, ambient temperature and the object’s surface temperature, the value of infrared camera’s emissivity is set as 1 and the infrared image’s temperature is got. Then, work out the total radiant emittance which was detected by the infrared camera in the theory of measuring temperature with infrared camera. After that, work out object surface emissivity. In order to verify the result’s veracity, set the value of infrared camera’s emissivity as the value, which was got from the last step. It could be directly concluded by comparing the infrared image’s temperature with the one that was got by means of non-infrared measuring ways. This measuring technology is simple in the measuring device, succinct in the techniques, and has the precise measuring result.
