Apparatus, systems, and methods for inspecting longitudinal surfaces and sidewalls of cut tubes are disclosed. In some embodiments, the apparatus includes a line camera, the line camera being configured to capture images of longitudinal surfaces of the cut tubes, an area camera joined with the line camera, the area camera being configured to capture images of sidewalls of the cut tubes, a mandrel and drive, a multi-axis motion stage, a vertical motion stage, and a rotating motion stage. In some embodiments, the system includes a camera module, a tube positioning module, a motion control module, and an analysis module. In some embodiments, the method includes positioning a line and area cameras, moving the cut tubes, capturing images of the longitudinal surfaces and sidewalls of the cut tubes, providing comparable images of a template cut tube, and comparing the images of the cut tubes to those of the template cut tube. |

1. An apparatus for capturing images of longitudinal surfaces and sidewalls of cut tubes, said apparatus comprising:
a line camera, said line camera being configured to capture images of longitudinal surfaces of the cut tubes; a rotatable, 360 degree area camera joined with said line camera, said area camera being configured to capture images of sidewalls around 360° of the cut tubes; a mandrel and drive adapted to hold and axially rotate the cut tubes about a Y-axis for positioning the cut tubes with respect to said line camera and said area camera; a multi-axis motion stage for moving the mandrel, drive, and cut tubes along an X-axis and along said Y-axis for positioning the mandrel, drive, and cut tubes with respect to said line camera and said area camera; a vertical motion stage for moving said line camera and said area camera along a Z-axis for positioning said line camera and said area camera with respect to the cut tubes; and a rotating motion stage for rotating said line camera and said area camera substantially about an X′-axis for positioning said line camera and said area camera with respect to the cut tubes. |
