Biospeckle Activity Evolution of Strawberries

Abstract

In this work, we measured the biospeckle activity of strawberries (fragaria × ananassa) with two recently developed algorithms. We observed an important diminution of speckle activity within time periods of 72 h. We tested the methods by analyzing different specimens to check for proper detection of bruised areas or fungal development. The obtained results serve as a starting point to correlate the time evolution of biospeckle activity with aging of fruits, in order to set the basis for development of future standardized fruit quality control procedures.
