摘要
为提高数字地震仪的分辨率和扩大动态范围，本文简要介绍了在地震仪设计中应用激光移频技术的新思路，简述了其基本原理及初步实验结果，用光ｆ干涉原理制作地震仪能够获得很高的准确度和较高的分辨率，动态范围可达１６０ｄＢ．
In order to raise the resolution and dynamic range of digital seismograph, this paper gave a brief introduction of a kind of new idea about frequency-shifted laser technology and its fundamental principle on designing seismograph.Also,it described the preliminary experimental results produced by using above-mentioned principle.A best accuracy and higher resolution could be obtained by the seismograph made based on this principle and the dynamic range could be enhanced to 160 dB.
