  • METHOD OF DETERMINATION OF GLASS SURFACE SHAPES AND OPTICAL DISTORTION BY REFLECTED OPTICAL IMAGING
    Publication number: 20100309328
    Abstract: A non-contact, opto-electronic method to determine glass surface shape involves pattern projection in reflection from a screen. The pattern is formed of black and white or coloured squares with a central reference pattern taken as origin of the x-y axes in the subsequent quantitative analysis of the optical distortion in formed glass sheets or panels.
