热释电探测器的电路设计与改进研究

The Study of Design and Improvement of Pyroelectric Infrared Detector Circuit

本文针对现有热释电红外传感器普遍存在的温差探测范围有限、输出信号弱和容易受到噪声的干扰等缺点,采用仿真模拟和实验验证相结合的方法,对热释电探测器电路做了进一步的研究和改进,获得了探测范围广、抗干扰能力强、高效稳定的红外探测器。

The pyroelectric infrared detector usually has three common problems such as limited temperature detection range, weak output signal,and susceptible to noise disturbance in the practical application.To solve above problems,we further research and optimize the pyroelectric detector circuit by using simulation and experiment method and achieve widely detection range,strong anti-interference ability,stable and efficient infrared detector.
