Determining density profile in plate-form material - moving two detectors in direction towards different measurement volumes to obtain scanning density profile, and both detectors are located on same side of endless plate

摘要

Wood-based plates are particularly involved and X-rays or gamma-rays are used from a source located on one side of the plane. Two directionally determined detectors are used, both of which are directed towards a desired measurement volume. The two detectors can be moved so that they are directed towards different measurement volumes, whereby with a scanning a density profile can be procured. The two detectors are located on the same side of the endless plate moved forward longitudinally during measurement. They are on the same side as the source or can be positioned on the opposite side to the source or the one detector can be positioned on one side of the plate whilst the other detector is on the other side of the plate.
