Mode-shape measurement of piezoelectric plate using temporal speckle pattern interferometry and temporal standard deviation

Optics Letters, 2011
This study proposes an image processing method to improve the quality of interference fringes in mode-shape measurement using temporal speckle pattern interferometry. A vibrating piezoelectric plate at resonance was investigated, and the full-field optical information was saved as a sequence of images.
