This paper presents a new spatial-temporal speckle correlation technique applied for quality evaluation of apples. Evaluations were performed using a nondestructive and noninvasive method based on the interpretation of an optical phenomenon that occurs when the fruit is illuminated with coherent light, referred as biospeckle. The temporal and spatial changes of speckle patterns created by laser light scattered in fruit have been measured through their correlation functions. The cross-correlation coefficient of biospeckle patterns decrease or increase in fruits with different speeds subject to conditions of their freshness, moisture and preservation. Significant exponential changes of the cross-correlation coefficient value difference Ct=15 were observed during apple shelf life. This shows that the method can be utilized for quality evaluation of apples. |
