1. An automated detection system for detecting materials of a glass-ceramic type among a cullet, comprising at least one white light source and at least one monochromatic ultraviolet light source, each being oriented to emit in a same emission region, an image acquisition device configured to acquire an image of said emission region and an image processing device configured to process each of the images acquired by the image acquisition device, the image processing device comprising a colorimetric image processing module configured to provide detection of glass-ceramic materials among other types of glass.
