摘要:
The invention relates to a system for the contactless optical detection of the position of an edge of a transparent article, especially of a plastic body. In order to detect an edge of the article a transparent plastic body is guided between two crossed polarizers and the incident light is twisted by the transparent plastic body in such a manner that an analyzer arranged below the crossed polarizers can detect the twisted light.
