1. A method for scanning an object in an inspection space comprising:

  • (a) scanning the object from a first perspective that is substantially orthogonal to a first plane starting at a first entry point in the inspection space that is adjacent a first edge of the inspection space to establish a first scan line trace of the object from the first perspective;

    (b) scanning the object from a second perspective that is substantially orthogonal to a second plane that is adjacent to but not co-planar with the first plane, starting at a second entry point on the second plane that is adjacent a second edge between the first plane and the second plane, to establish a second scan line trace of the object from the second perspective;

    (c) providing relative motion between the object and the first scan line trace and the second scan line trace; and

    (d) repeating step (a), step (b), and step (c) at least once such that the repetition of step (a) produces a first two-dimensional image of the object comprising multiple first image scan lines from the first perspective and step (b) produces a second two-dimensional image of the object comprising multiple second image scan lines from the second perspective.
