The reflectivity of body is not quite similar, but the emissivity in infrared probe is then set as a fixed value, in practical measurement process
Then there are larger errors for the testing result of acquisition.Authorization Notice No. for CN101435721B (application No. is
200810134154.4) Chinese invention patent《Infrared target temperature correction system and method》, wherein being connect using emissivity
The target for being bordering on 1 is corrected work.In actually measuring, emissivity and the infrared probe of object to be measured body carry out temperature calibration
The reflectivity of Shi Xuanyong black matrixes is difficult to be consistent, and the gap of this reflectivity can directly affect infrared probe to target temperature
Measurement result.
