Abstract
Disclosed is a method and a device for optically analyzing fruit or vegetables. Different light sources are adapted to apply light radiation in different wavelength ranges selectively to each object according to a predetermined illumination sequence, and images are produced by at least one color camera sensitive to infrared, the exposure of which is controlled in synchronism with the illumination sequence so as to produce a plurality of images in different wavelength ranges, including at least one image in a visible range and at least one image in an infrared range.
