An x-ray diffraction imaging device includes at least one x-ray detector and at least one scatter collimator positioned upstream of the at least one x-ray detector. The at least one collimator includes a plurality of successive plates. Each of the plurality of plates defines a plurality of rectangular holes. The plurality of successive plates are arranged such that the plurality of rectangular holes define a plurality of quadrilateral passages extending through the at least one scatter collimator. Each of the plurality of quadrilateral passages is configured to increase a rate of detection of first x-rays that define an x-ray transit path enclosed within a single such quadrilateral passage. Also, the plurality of quadrilateral passages is configured to decrease a rate of detection of second x-rays that define an x-ray transit path that intersects more than one such quadrilateral passage.

X-ray diffraction device, object imaging system, and method for operating a security system

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.
