【摘要】 本文给出了超高频区(MH_z以上)SBN热电探测器阻抗随频率变化的测量结果,考虑到压电谐振和电极引线的影响分析了该阻抗特性。本文认为利用阻抗谐振特性可使器件的响应率提高1/tgδ倍。更多还原

【Abstract】 The impedance measurments of SBN pyroelectric detector are obtained at very high frequencies. Considering the Piezoelectric zesonance of SBN and the effect of leading wire, the impedance and responsivity of pyroelectric detector are analyzed. It is clear that there is a large increase in responsivity at tuning frequency.更多还原
