<p>The present invention relates to a method for automatically inspecting and/or sorting in order to analyze and/or distinguish, within a flux, objects belonging to at least two separate categories on the basis of the chemical composition. The method involves providing a substantially single-layer flow of randomly arranged objects passing over a predetermined width; projecting a laser flux that is shaped within an analysis area having the objects passing therethrough; collecting and shaping the detection signals corresponding to the responses output by each object affected by the laser flux; processing and assessing the collected and shaped detection signals, synchronized with the projection of the laser flux, by means of an adapted analysis device that makes it possible to distinguish between the objects. Said method is characterized in that it also involves: dividing the original incident laser flux (3) into a plurality of collimated or focused secondary beams (3') and simultaneously applying the latter at points spaced apart and distributed within the analysis area (4); and simultaneously collecting, in parallel, the detection signals generated by each secondary beam (3') on contact with an object, item, or piece (1) within the analysis area.</p> |
