Abstract
A method and apparatus for sorting is described, and which includes an arrangement for controllably and operably coupling to a controller, and then selectively energizing each of a background element; laser scanner; first and second electromagnetic radiation detectors; line scan imaging assembly; and selectively energizable radiators, so as to improve the detection of individual products and/or other objects of interest forming a product stream by increasing the contrast of the respective products or specific characteristics thereof, and/or objects of interest in a multiplicity of electrical signals which are received, and then processed by the controller, as the product stream passes through an inspection station.
