<p>Apparatus for the optical inspection of transparent preforms, and comprising illuminating means, means for detecting luminous images and generating electric signals corresponding to such images, as well as means for processing and comparing these electric signals, in which said means for detecting luminous images are constituted by a single image pick-up means and, as it moves between said illuminating means and said image pick-up means, each one of said transparent products is picked up, ie. shot in a plurality of distinct orientations by said single image pick-up means. To each one of said distinct orientations corresponds a distinct different position of the respective preform between said image pick-up means and said illuminating means.</p> |
