Abstract: An apparatus for detecting matter including: a light source arrangement adapted to emit a first and a second set of light beams towards a first detection zone through which the matter is provided. A spectroscopy system adapted to receive and analyse light which is reflected and/or scattered by matter in the first detection zone. A laser triangulation system including, a laser arrangement adapted to emit a line of laser light towards a second detection zone. A camera-based sensor arrangement configured to receive and analyse light which is reflected and/or scattered by matter in the second detection zone. The received light of the spectroscopy system completely or partially intersects the received light of the camera-based sensor arrangement and/or the line of laser light.

Abstract: A method for object classification, including: guiding a continuous stream of objects from a transport mechanism directly into an unsupported path, along which the object stream is fed through a detection region; illuminating the detection region with a radiation band in a first direction; optically scanning the detection region to detect electromagnetic radiation reflected by the at least one object in the detection region by viewing the detection region along a second direction, wherein the directions have a cross-section in the detection region and form an angle relative each other of 10°-80°; analyzing the information; and classifying objects in at least two different directions based on the analysis of the transparency information from the optical scanning; wherein the step of analyzing the information from the optical scanning includes analyzing the objects based on the intensity, spread and texture of the detected radiation from the optical scanning.
