高精度激光测振系统的原理及应用

摘要
在物探地震勘探施工过程中,检波器的具体工作状况直接影响着采集数据的质量。为了进一步提高物理勘探的质量,建立了物探专用质检实验室,并配置了高精度激光测振系统,用以检测检波器的各项性能指标。该系统经过一二年的实际运用,表现出良好的测试性能并提供了高精度测试数据。本文介绍了检波器及高精度激光测振系统的工作原理,用实例重点介绍了使用高精度激光测振系统测试检波器指标和利用典型特性曲线来分析检波器工作状况的应用情况。
In the field operation of geophysical prospecting,the working situation of geophone directly influences the acquired data quality.In order to further improve the exploration quality,a special quality inspection geophysical lab is established.And in the lab there is a high precision laser calibration system,which has been put in used for detecting the performance of geophones.More than one year application,this measurement system proved to be of high testing performance and high precision.This paper introduces its working principle and describes how to use the detecting data and characteristic curves to analyze the status of geophone.
