摘　　要：近些年来,红外成像系统的性能评估一直备受关注,是红外成像系统关键技术发展的不可分割的一部分,文章对于红外成像系统的特性进行介绍,通过时间轴的方式对系统评估的发展过程进行介绍,并针对红外成像系统静态性能模型中的信号传递函数、最小可辨温差、调制传递函数和噪声等效温差主要性能参数的测量方法原理进行研究综述。归纳出目前主要使用的测试方法。In recent years, the evaluation of infrared imaging system is always a hot topic. It is an essential part of the development of infrared imaging system. The characteristics of infrared imaging system are analyzed, and the status of infrared camera system classification is introduced. With the development of time, the article introduces the development of infrared imaging system evaluation. Signal transfer function, the minimum resolution temperature difference of the system, modulation transfer function of the system and noise equivalent temperature difference are summarized and researched. Summed up the test methods are used frequently.
