| | Abstract | | We evaluated the monitoring performance of a small ACROSS device developed by Kyushu University and developed analysis method. We compared transfer functions and dispersion curves obtained from the small ACROSS device operated with a 10-30Hz frequency range with those from the large ACROSS device operated with 5-15 Hz. In the frequency range of the small ACROSS, we observed high temporal stability of the transfer functions and dispersion curves. The transfer functions and dispersion curves obtained from the small ACROSS were consistent with the large ACROSS in the common frequency range (10-15Hz). In addition, stable transfer function and dispersion curve with the information of the wide frequency range could be obtained by combining the small ACROSS and the large ACROSS data with different frequency ranges. |
