摘　　要：介绍了线性度测试的定义及测试方法。测试了中波红外焦平面器件的线性度,并针对实验室测量线性度带来的误差进行分析,为红外焦平面器件线性度的测量提供理论和实验依据。该实验证明了测试线性度中黑体发射率误差是致命因素;同时也测得一款中波红外焦平面产品的线性度标准偏差小于0.02 V。Definition of infrared FPA linearity, calculation and test principle are introduced. Linearity of a middle wave infrared FPA detector was tested. Test error of the linearity was analyzed. The test results can provide theoretical and experimental foundations for measuring the linearity of infrared FPA detector. The experiments prove that the error of blackbody＇s emissivity is the lethal factor in linearity measurement. The standard deviation of a middle wave infrared FPA＇s linearity was tested and it is less than 2%.
