Abstract
A gauging system is provided for measuring glass flatness and thickness, in which a glass sheet is accurately supported on a reference plane, and fiber optic sensors are lowered toward the glass to sense the location of the upper and lower surfaces of the glass sheet. The sensors send signals, which are representative of the locations of the surfaces, to a central processing unit which is used to calculate thickness and/or flatness of the glass sheet.
