Abstract: A glass sheet thermally strengthened such that at the first major surface is under compressive stress; the sheet having an a characteristic 2D autocorrelation matrix c(x,y) given by c(x,y)=F−1(F(g)·F̂(g)) where F is a 2D Fourier transform and ̂ represents a complex conjugate operation and g is a high pass filtered data array given by g(x,y)=F−1(F(f(1−F(h)) where h is a spatial 2D low pass filter array and f is a square data array of Shear 0 and Shear 45 data, taken over an area away from any birefringence edge effects on the sheet, wherein an autocorrelation peak maximum width of the matrix c(x,y) at 40% of peak height, for the c(x,y) matrices from both the Shear 0 and Shear 45 data, is between 1 and 5 mm.

Abstract: Methods of processing a viscous ribbon include supplying a molten material from a supply vessel. Methods include forming the molten material into the viscous ribbon. The viscous ribbon travels along a travel path. Methods include receiving thermal light energy produced from the viscous ribbon. Methods include generating an image of the viscous ribbon from the thermal light energy. Methods include detecting a defect of the viscous ribbon from the image.

Abstract: A method of measuring geometric parameters of through holes in a thin substrate includes acquiring images of select sub-volumes of the substrate using an optical system having a field of depth greater than a thickness of the substrate. The acquired images are processed to determine the desired geometric parameters.
