研制成功一种新型结构LiTaO_3热释电红外探测器。用一种特殊的粘合剂把探测材料安装在一个电导体上,该粘合剂具有高电导率和低的热导率。理论计算出这种新型热释电探测器的热释电响应率和D与热释电元件厚度的函数关系。实验证实了响应率和D对厚度之间的依赖关系,表明理论计算与实验结果相符。
Developed a new type of LiTaO_3 pyroelectric infrared detector. The probing material is mounted on an electrical conductor with a special adhesive that has high electrical conductivity and low thermal conductivity. The pyroelectric response of the new pyroelectric detector and the function of D as a function of the thickness of the pyroelectric element are calculated theoretically. Experiments confirmed the dependence of response rate and D on the thickness, indicating that the theoretical calculation is consistent with the experimental results.
