Abstract:
A system and method that includes, in an embodiment, a prism, a camera, a light source, and a plate. The system, in an embodiment, is configured for scanning a roll and generating an image of the roll surface. The prism, in an embodiment, is positioned below the camera and above the plate. In an embodiment, the plate is positioned below the prism and above the roll surface. In an embodiment, the light source is positioned above the prism. In an embodiment, the light source and the prism are positioned to provide light to the roll surface at an angle of at least 75 degrees measured from a line normal to the roll surface. In an embodiment, the prism is configured to refract light from the light source, the camera is a line scan camera that includes a row of pixel sensors, and the light source includes light emitting diodes.
