| Abstract(in English) | Buried object which exists at extremely shallow underground (about within 10cm) can be detected by using an acoustic vibration and a scanning laser Doppler vibrometer (SLDV). We have already confirmed that the detection and identification of the buried object is possible by using the optimum frequency range method (OFR). However, only the amplitude of the vibration speed spectrum is used conventionally. Therefore we study about new imaging method that used the phase of the vibration speed spectrum. As a result, we confirmed the possibility of the outline extraction by using the phase difference between each scan point. |
