Zusammenfassung:Methods of inspecting a material include moving the material and identifying a defect location of a defect. Methods include moving a camera along a second travel path in a second travel direction such that a field of view (FOV) of the camera moves relative to the material along the second travel path to match the defect location. Methods include passing the defect through the field of view (FOV) as the material moves and capturing images of the defect with the camera as the material moves and the defect moves through the FOV. The images include a first image of a first major surface, a second image of a second major surface, and a third image of an intermediate portion of the material between the first major surface and the second major surface. Methods include reviewing the plurality of images to characterize the defect.
