Abstract
Methods of operating an automated optical inspection system to separate selected items, e.g., grape stems (124, 126, 128), grape leaves (122), or rocks from a mixture (16) of those items and raisins (120) include illuminating the mixture with illumination (37', 37') characterized by a spectral power distribution (86, 98) in the near infrared (88, 90, 100, 102), detecting reflections of wavelengths of the illumination in the near infrared, identifying the selected items based on the detected reflections, and sorting the selected items from the mixture.
