振动噪声对长波快速响应热释电红外探测器的实际应用影响较大,减少振动噪声是热释电探测器研究的重要内容之一。提出采用自适应滤波的方法来降低振动噪声,并且就这种方法进行了讨论。
Vibration noise has a great influence on the practical application of longwave fast response pyroelectric infrared detector. Reducing vibration and noise is one of the important contents of pyroelectric detector. The method of adaptive filtering is proposed to reduce the vibration noise, and this method is discussed.
