MRTD是评价热成像系统综合性能的重要参数。分析了热像仪参数测试系统的两种基本结构，比较各自的优缺点，给出了各自应用场所。研究了MRTD测试对热像仪参数测试系统各组成单元的具体要求。根据 MRTD 参数的特点，分析了引起 MRTD 测试结果一致性较差的原因，给出了相应的解决措施和修正方法。为验证解决措施和修正模型的正确性，以一个热像仪为例进行了M RT D测试，并将测试结果与该热像仪的出厂结果比对，测试结果偏差小于15%。实验表明，该修正模型可以提高MRTD测试结果的重复性和准确性。

MRTD is an important parameter to evaluate the comprehensive performance of thermal imaging systems. The structure of two common test systems for testing thermal imagers is analyzed, whose advantages and disadvantages are compared and their application is given. The specific requirements on each part of test system are studied. According to the characteristics of MRTD, the causes of MRTD test result’s poor uniformity is analyzed, and the corresponding solution and correction model are given. In order to test and verify the correctness of the solution and correction model, a thermal imager is used as an example for MRTD testing. Compared with the test results of manufacturer, the maximum deviation is less than 15%. The test results show that the correction model can improve repeatability and accuracy of MRTD test results.
