METHOD AND APPARATUS FOR ILLUMINATING MATERIAL FOR AUTOMATED INSPECTION |
摘要 |
A lighting configuration that is a combination of far dark field lighting and a modified dark stripe lighting is disclosed. The novel combination provides a more robust detection of flaws on, e.g. a moving web of transparent film, than either would provide alone or through a summation of their individual parts.
