SYSTEM AND METHOD FOR MEASURING A SURFACE IN CONTOURED GLASS SHEETS

An optical inspection system is provided for an ultraviolet laser and associated optics forming a planar laser sheet directed to a glass sheet. The planar laser sheet intersects a surface of the glass sheet thereby causing the surface of the glass sheet to fluoresce and form a visible wavelength lin...

Zusammenfassung:	An optical inspection system is provided for an ultraviolet laser and associated optics forming a planar laser sheet directed to a glass sheet. The planar laser sheet intersects a surface of the glass sheet thereby causing the surface of the glass sheet to fluoresce and form a visible wavelength line on the surface. A camera has an image sensor for detecting the visible wavelength line. A control system in configured to receive image data indicative of the visible wavelength line, analyze and triangulate the data to determine a series of coordinates associated with the line, and create a three-dimensional map of the surface of the glass sheet as a function of the series of coordinates. Methods for using an optical inspection system, for gauging a surface using an optical inspection system, and for providing optical reflectance information for a surface using an optical inspection system are also provided.
