摘要
地震检波器是一种将机械振动转换为电信号的专用传感器。文章介绍了数字检波器和光栅检波器的原理及特点,并且从模拟和数字两个领域对模拟和数字检波器的结构和性能做了比较,同时对检波器选用的基本原则进行了介绍。
The seismic geophone is a special sensor for converting mechanical vibration into electrical signal. This paper introduces the principles and characteristics of the digital geophone and grating geophone,and compares the structure and performance of the digital geophone with the analog geophone. This paper also proposes some basic principles about choosing of the geophone.
