为解决普通热释电的红外探测技术误报率高、敏感度低且不能对入侵目标进行定位等问题,提出了一种基于热释电红外探测器的复眼结构的设计。结合热释电红外探测隐蔽性好、性能稳定、环境适应能力强、复眼视场角大、体积小且灵敏度高等优势,将热释材料上的电荷信号转换为电压信号,经滤波、放大后输出。通过实验表明,采用该热释电红外探测器的单目可以检测到15 m内的入侵目标,并输出脉冲电平作为报警信号。

To solve the problems of high false alarm rate,low sensitivity and unable to locate intrusion targets and other issues in ordinary pyroelectric infrared detection technology,the design based on compound eye structure is proposed for pyroelectric infrared detector. Combining the advantages of pyroelectric infrared detection,including good concealment,stable performance,environmental adaptability,large viewing angle of compound eye,small size and high sensitivity,the charge signal on pyroelectric material is converted into voltage signal,and output after filtering and amplifying. Experiments show that the monocular of the designed pyroelectric infrared detector can detect intrusion target within fifteen meters,and output pulse level as an alarm signal...
