Starting from analyzing the current situations of grating digital geophone, the paper analyzed in detail the principle of grating digital geophone and processing approaches of output signals.
本文从分析数字检波器的现状着手，对光栅数字检波器的原理及其输出信号的处理方法进行了详尽地分析。
There is the non-detected component in the output of geophone. This component is called the pseudo signal response, which seriously affects the quality of seismic data.
检波器的输出信号中存在着非测量的成分，我们称之为检波器的伪信号响应，它严重地影响地震勘探数据的质量。
