Abstract
This paper is focusing on studying the Infrared radiation temperature measurement system. The signal-to-noise ratio, sensitivity and detection accuracy of infrared detection system is analyzed in detail based on the target irradiance received by the detector pixels in the unit solid angle. Structure design and key parameters of the infrared detection system was introduced and calibration of the surface uniformity was carried out in detail. The background compensation model is set up for industrial field experiment. Then comparison experiments between the infrared detection system and the infrared radiation thermometer were implemented. The experiment results show mean difference is 0.15℃ and standard deviation is 4.4℃, so it can satisfy the requirements of industrial field temperature measurement accuracy. And technical challenge of temperature monitoring for tube surface is solved in high temperature environment.
