Abstract
An apparatus and associated method for measuring transmitted optical distortion in a glass sheet includes a glass stand which receives a glass sheet for mounting between a background screen which includes a matrix of spaced apart dots, and a digital camera which captures (1) an image of the glass sheet surface, and (2) an image of the dot matrix transmitted through the glass sheet. The captured images are downloaded to a computer that is suitably programmed to analyze the image data to (1) determine the presence of any markings or elements on the surface of the glass sheet that should be isolated from the dot matrix image, (2) modify the background image to eliminate the image data corresponding to any such surface markings or elements from the image, and (3) determine characteristics indicative of optical distortion in the modified image of the dot matrix background transmitted through the glass sheet.
