Abstract
Abstract A method and an apparatus for optical inspection of transparent articles. The method and apparatus use a light beam scanning field which is separated into at least two portions. The field portions are directed at the article at differing angles of incidence such that they eliminate blind spots caused by portions of the apparatus which block the passage of the light through the article. A feature of the invention is its provision of a folded optical path to increase the length the beam travels between the beam generator and the object beyond the physical distance between the beam generator and the object.
