GLASS INSPECTION SYSTEM

摘要

An inspection system for a sheet of glass. The system comprises a first laser and a second laser, each of which provide a sheet of light, a cylindrical lens system, and a first light detection system and a second light detection system. The first laser is located at the focal point of the lens system. The second laser is located at a distance from the lens system that is greater than that of the first laser, and off of the axis of the lens system. The first light detection system receives light from the first laser and the second light detection system receives light from the second laser. The inspection system is adapted to position a sheet of glass between the lens system and the detection systems. A method is also described.
