Abstract: An apparatus and associated method for measuring both transmitted optical distortion and other minimal visible defects in the surface of a glass sheet. The disclosed apparatus includes a glass stand which receives a glass sheet for mounting between a background screen which includes a pre-defined contrasting pattern, and a digital camera which captures an image of the pattern transmitted through the glass sheet. The digital image is downloaded to a computer that is suitably programmed to analyze the image data to determine (1) optical distortion indicia, including the magnification and lens power, in the observed image of the pattern transmitted through the glass sheet, and (2) small visible optical or obstructive defects on the glass sheet.

Abstract: 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 is 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.
