摘要
详细论述了热释电探测器的工作原理，推导出探测器电流响应率、电压响应率、等效噪声功率和探测率的解析表达式，得出了电压响应率、电流响应率与斩波频率的关系。给出热释电材料的选择原则，介绍了热释电探测器的目前应用领域及未来可能的应用领域。
This paper reviews the prindples of operahons of pyrocledc detectors, The equations for current responsivity, voltage responsivity, noise, noise equivalent power and detectivity derived from the fundamental thennodynot model of the pyroelectric detector .Fibers influendng the choice of pyroelectric material for various applicahons are briefly summerized. The applicahons are discuss.
