11 September 2012Laser speckle dynamic for monitoring fruits maturation
Our study is based on using a non-invasive technique, the bio-speckle technique, in order to follow the ripening
of fruits during different stages: before and after the climacteric stage. To assess the impact of the ripening
of fruits on their optical properties, speckle grain is measured and the variation of its dimensions is evaluated.
In addition, and in order to correlate this observation with the degradation of chlorophylls, both a physical
approach based on recording the fluorescence spectrum of chlorophylls, and a biochemical approach based on a
pigmentation analysis, are used. We therefore show the efficiency of biospeckle metrology for monitoring fruit
