Characterization of Shear Horizontal Waves Using a 1D Laser Doppler Vibrometer

Characterization of Shear Horizontal Waves Using a 1D Laser Doppler Vibrometer

We developed a new technique for the detection of shear horizontal surface acoustic waves (SH-SAW) using a one-dimensional laser-based Doppler vibrometer. It measures the out-of-plane surface deformation at the fingertip of an interdigitated transducer (the boundary of the wave aperture) and uses it...
