Optical Detection of Surface Defects in Oranges

An optical-based sorting device for oranges is presented. Its design has been based on homogeneity of illumination and detection of the light reflected and scattered by the fruit. Several configurations are studied and compared under semiempirical formulations .A general purpose microprocessor based hardware is proposed. A sorting rate over 10 fruits per second on each channel is achieved.
