Fully Noncontact Wave Propagation Imaging in an Immersed Metallic Plate with a Crack

<table>Typical time domain waveforms extracted at (20 and 25) in Figures <a href="../fig6/#a">6(a)</a> and <a href="../fig8/#b">8(b)</a> for SNR evaluation (waveform comparison after single scan and 10× repeat scan for water-immersed plate condition) and definition for SNR calculation.</table>
