Abstract
An inspection system for the edge of a sheet of glass e.g. automobile glass. The system has at least one laser, with the laser beam directed at the edge of the glass. Light reflected from the edge is recorded e.g. with a camera. The path length from the laser to the glass edge and back to the camera is maintained constant as the glass moves through the apparatus.
