1. Apparatus for automatically inspecting matter for varying composition, comprising advancing means for advancing a stream of said matter, a detection station through which said stream passes, emitting means serving to emit a detection medium to be active at a transverse section of said stream at said station, said transverse section being comprised of a multiplicity of individual detection zones distributed across substantially the width of said stream, receiving means at said station arranged to extend physically across substantially the width of said stream and serving to receive detection medium varied by variations in the composition of said matter at said section, detecting means arranged to be in communication with said receiving means and serving to generate detection data in dependence upon the variations in said medium, and data-obtaining means connected to said detecting means and arranged to use the detection data from said individual detection zones to construct a two-dimensional simulation of said matter passing through said detection station.
