Abstract
A biological activity phenomenon, the cyclose that occurs in citrus fruits or in seaweed, is analysed by using the temporal correlation of speckle patterns produced when a specimen is illuminated with a laser beam. The experimental verification of the phenomenon as well as a theoretical model of the distribution of the elementary moving particles are given. Specific statistical processing of the digital speckle is applied to the computation of correlation coefficients. Experimental results are given for three kinds of biological samples.Keywords
