Principle And Error Analysis Of Infra-Red Temperature Measurement |
| |
| Abstract: | In this paper, the theory and mathematic model of infrared temperature measurement was established according to the principle of blackbody radiation. The main factors for measurement accuracy are analyzed, such as reflectance, environment and distance coefficient. Then the interrelationship between the ambient temperature and object temperature from experiment data were obtained. |
