DOI: 10.1109/tim.2023.3267528
Abstract: Wavefield measurements by a scanning laser Doppler vibrometer (LDV) are generally carried out in a Cartesian coordinate. As a piezoelectric transducer generates Lamb waves following radial paths, the use of a polar coordinate can be… read more here.

Abstract: We propose two strategies for eliminating the speckle noise in a laser Doppler vibrometer according to Fourier analysis. Fourier transform is theoretically conducted on the speckle pattern phases, whose variation dominantly contributes to the speckle… read more here.
