Abstract: An apparatus for detecting matter comprises bulk feeding means configured for feeding a plurality of objects into a detecting region; at least one light source having a focusing element and being configured for illuminating at least one object moving in an object plane in the detecting region; and a first light-analyzing apparatus arranged to sense light that has been transmitted through the object. In the associated method, the object is caused to move in the plane and the object is illuminated with incident light. Light that has been transmitted through the object and is falling in a measuring plane is detected, and an object-specific parameter based on the detected transmitted light is determined.

Abstract: An apparatus for inspecting a stream of matter including: a first and a second light source for emitting a first and a second light beam; a first and a second detector; a first scanning element adapted to redirect the detection area of the second detector from side to side across said stream, and a beam splitting element arranged to receive said first and second light beams, after they have been reflected against said matter, wherein said beam splitting element is adapted to guide said reflected first light beam towards said first detector and to guide said reflected second light beam towards said second detector.
