Abstract: Methods and apparatus for reducing detection of x-ray scatter in an x-ray system are described featuring one or more x-ray sources, one or more sensors, one or more field blocks configured to limit the field of view of the one or more sensors, one or more collimators configured to direct x-rays generated by the one or more x-ray sources in the direction of the one or more sensors, and a relative motion mechanism configured to alter a position of an object under inspection relative to the x-ray source and the one or more sensors.

Abstract: An x-ray inspection system. The x-ray inspection system includes an x-ray source, an on-axis x-ray sensor, at least one off-axis x-ray sensor, a fixture, and an accumulation circuit. The on-axis x-ray sensor is configured to capture on-axis images of radiation from the x-ray source. The x-ray source is displaced from the on-axis x-ray sensor, and the x-ray source and the on-axis x-ray sensor are positioned on an axis conceptually drawn between the x-ray source and the on-axis x-ray sensor. At least one off-axis x-ray sensor is configured to capture off-axis images of radiation from the x-ray source, wherein each off-axis x-ray sensor is positioned off the axis. The fixture is configured to maintain an article between the x-ray source and the on-axis and off-axis x-ray sensors, and the accumulation circuit is configured to receive and accumulate images captured by the on-axis and off-axis x-ray sensors.

Abstract: A scanning apparatus having a linear photosensor, an imaging assembly, and a scanning displacement assembly adapted for producing relatively constant rate linear displacement between an imaged object and the imaging assembly to cause scan line portions of the object to be sequentially imaged on the linear photosensor device and an image registration holding assembly associated with the scanning displacement device to cause an image from each different scan line portion on the object to be temporarily held in registration with the linear photosensor.

Abstract: A color optical scanner for generating data representative of a color image of an object which is scanned including: a linear sensor array located on an image plane for generating a data signal indicative of the intensity of light impinged thereon and having sensor sampling intervals of a predetermined length; an imaging assembly for imaging a moving scan area on the object containing a plurality of scan lines on an image plane and for defining an imaging light path extending from the scan area on the object to the image plane; a color wheel positioned along the imaging light path and having an axis of rotation extending transversely of the light path and having a plurality of faces adapted to be sequentially rotated into intersecting relationship with the light path; a plurality of the faces including a plurality of filter portions of different spectral range transmissibility which are sequentially rotated into intersecting relationship with the light path during different color imaging intervals having dura
