ABSTRACT:
A system for high-speed inspection is provided. The system includes a digital camera focused on an inspection location and generating image data. An array of light emitting diodes generates light beams, and one or two lenses collimate the light beams. The angle of incidence of the collimated light on an item at the inspection location is greater than approximately 50 degrees, such as to avoid flashing which can be created by coating on the inspection item or other surface effects. The collimating lenses have a center hole and the digital camera is focused on the inspection location through the center hole.
