| 摘 要： | 针对铁电材料BST的电容在直流偏场下电性能随温度变化,设计了一种用来检测微小差分电容的电路。采用性能、形状较为一致的BST铁电陶瓷单元电容器配对结构,以电脉冲的方式读取不同温度下材料的充放电电荷数,从而探测辐射到铁电材料上的红外信息。实验结果与理论分析较为吻合,中心频率10Hz、带宽2Hz、放大倍数9000倍。这种BST红外探测器阵列像元信号检测电路具有抗寄生电容干扰强、灵敏度高、容易实现、成本低等优点。改进该探测电路,有望开发出结构简单、性能优良的新一代红外探测器。

| Abstract: | Aiming at the changes in the electrical properties of BSTs with the temperature under DC bias field,a circuit to detect the micro-differential capacitance was designed.The IR radiation detection property was researched by using the BST ceramic double-capacitors with similar characteristic and structure.The charge and discharge number at different temperatures was read out by the electric pulse,and thus the information of infrared radiated into the ferroelectric material could be detected.The experimental re... |
