We have measured the growth of vegetable leaves in real-time by means of digital speckle correlation to detect speckle displacement caused by the growth. We employed two optical configurations, the first for detecting strain component by a pair of CCDs and the second for detecting in-plane translation by a single CCD. We could clearly observe the influence of white light irradiation on the growth rate.
