在文章中，以一个实际系统为例，给出了测试这四个基本参数所用到的测试原理、测试设备以及试验安排，并将理论值和测量值进行了比较，分析了误差的原因。
as the microbolometer which is voltage biased express some characters different from other infrared detectors under the effect of electric heat and infrared radiation together, the computing method of parameters, such as responsivity, noise, noise equivalent temperature different ( netd ), noise equivalent power ( nep ), optical gain, detectivity and so on is given in this paper . some of these parameters are particular compared with other detectors, and some have difference between microbolometer and other detectors
由于微测辐射热计在施加偏置电压的情况下，电热效应与红外辐射的共同作用使它表现出与其他红外探测器完全不同的一些特征，文中给出了响应率、噪声、噪声等效功率、噪声等效温差、光学增益、探测率等参数的计算方法，这些参数中的部分是微测辐射热计独有的，或者与其他的红外探测器的同一参数有所区别。
