Non-uniformity Correction Technique for IR Imaging Based on Thermoelectric Reference Sources
摘要
Abstract
Non-uniformity of the IR imaging changes with time and temperature, so correction effect based on laboratory calibration deteriorates over time. To maintain the accuracy during an extended time imaging, the calibration needs to be frequently repeated, which makes standard blackbody source unsuitable for the calibration. To solve this problem, a non-uniformity correction technique based on thermoelectric reference source is introduced and a radiation source is mainly described to be inserted into the optical path at the command of calibration. Experimental results show that the reference source introduced here has high stability and its fluctuations can be controlled within 0.04 K when temperature ranges 10 K in the ambient environment. This method can significantly reduce the deterioration of the non-uniformity over time.关键词
