Zusammenfassung:The optical quality of float glass is determined by shadowgraph at a suitable location in the line for manufacturing the sheet of float glass. The image is recorded by a video camera and evaluated with the aid of digital image processing so as to determine the brightness profiles. The refraction profile is calculated from the brightness profile and is represented and evaluated numerically and/or graphically.
