| Abstract: | 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. |
