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

open access: yesOptics 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.
