Abstract: An x-ray diffraction imaging (XDI) device includes at least one x-ray source configured to emit an x-ray fan-beam. The XDI device also includes a primary collimator positioned downstream of the at least one x-ray source. The primary collimator defines a plurality of rows of slits. Each slit and each row of slits is separated by an x-ray absorbing material. Each of the rows of slits oriented to transmit at least one x-ray slit-beam in a plane substantially orthogonal to the primary collimator.

Abstract: A detection system includes a multi-focus radiation source configured to generate X-ray radiation and a primary collimator defining a first row of apertures and a second row of apertures. The first row of apertures forms first X-ray beams within a first plane from the X-ray radiation, and the second row of apertures forms second X-ray beams within a second plane from the X-ray radiation. The first plane is different than the second plane. The detection system further includes a scatter detector including a first row of scatter detector elements and a second row of scatter detector elements. The first row of scatter detector elements is configured to detect scattered radiation from the first X-ray beams, and the second row of scatter detector elements is configured to detect scattered radiation from the second X-ray beams.

Abstract: A multiple-plane X-ray diffraction imaging (XDI) device for generating an X-ray diffraction (XRD) profile of an object is described. The XDI device includes an X-ray source configured to generate X-rays and a first primary collimator configured to generate a first primary X-ray fan-beam. The XDI device also includes a second primary collimator configured to generate a second primary X-ray fan-beam. The XDI device also includes a first scatter detector array configured to detect a first set of scattered radiation generated upon intersection of the first primary X-ray fan-beam with the object, and a second scatter detector array configured to detect a second set of scattered radiation generated upon intersection of the second primary X-ray fan-beam with the object.

Abstract: A method for operating an X-ray diffraction imaging (XDI) system to scan an object includes generating an X-ray beam from at least one source focus at a first focus location, and receiving first scatter radiation at a first scatter angle at a scatter detector. The first scatter radiation is produced when the X-ray beam interacts with the object. The method further includes displacing the at least one source focus from the first focus location to a second focus location, generating a displaced X-ray beam from the at least one source focus at the second focus location, and receiving second scatter radiation at a second scatter angle at the scatter detector. The second scatter radiation is produced when the displaced X-ray beam interacts with the object. An identification of the object based on one of the first scatter radiation and the second scatter radiation is output.

Abstract: 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.
