摘要：
A dynamic electronic speckle pattern interferometry (ESPI) method was applied to study the blooming process in two kinds of flowers, the lily and the tulip. The complicated displacement fields of the flower petals were precisely monitored throughout the entire blooming process. The optical setup is a Fizeau type interferometer with relatively high robustness to air turbulence and vibrations. For quantitative evaluation of the displacement field, the subtraction-addition method (SAM), which utilizes only the digital signal processing of a sequence of images, was implemented. Measurements with accuracy in the range of lambda/10 were achieved.
