Abstract
A secondary collimator for an X-ray scattering device with horizontal plates and vertical plates arranged perpendicular thereto, the vertical plates being arranged parallel to one another and being inclined by a pre-determinable scattering angle to a transmission direction of an X-ray beam, and the horizontal plates being aligned fan-shaped onto a single point, namely to the X-ray source, and the horizontal plates with the vertical plates forming a rectangular grid with the vertical plates and being combined to form a collimator unit. Moreover, the invention relates to an X-ray scattering device for baggage check with an X-ray source, with a primary collimator which only lets through a fan beam, with a secondary collimator for projecting an area of an item of luggage and with a scattering detector, the secondary collimator being arranged between the item of luggage to be examined and the scattering detector and being developed as mentioned above.
