Patent number: 11860090Abstract: Systems and methods of performing a stress measurement of a chemically strengthened glass using a light-scattering polarimetry system include adjusting the intensity of a light beam from a light source in an illumination system using a rotatable half-wave plate and a first polarizer operably disposed between the light source and a rotating light diffuser that has a rotation time tR. The first polarizer is aligned with a second polarizer in a downstream optical compensator to have matching polarization directions by rotating the rotatable half-wave plate to a position where the exposure time tE falls within an exposure range tR?tE. The method also includes performing an exposure using the exposure time tE to obtain the stress measurement. One or both of the half-wave plate and first polarizer can be tilted to avoid deleterious back-reflected light from entering the light source.Type: GrantFiled: March 31, 2022Date of Patent: January 2, 2024Assignee: CORNING INCORPORATEDInventors: Ryan Claude Andrews, Pierre Michel Bouzi, William John Furnas, Jacob Immerman, Jeremiah Robert Jacobson, Katherine Anne Lindberg, Evan Lewis Olson, Nathaniel David Wetmore

Patent number: 11852549Abstract: The hybrid measurement system includes an evanescent prism coupling spectroscopy (EPCS) sub-system and a light-scattering polarimetry (LSP) sub-system. The EPCS sub-system includes an EPCS light source system optically coupled to an EPCS detector system through an EPCS coupling prism. The LSP sub-system includes an LSP light source optically coupled to an optical compensator, which in turn is optically coupled to a LSP detector system via a LSP coupling prism. A support structure supports the EPCS and LSP coupling prisms to define a coupling prism assembly, which supports the two prisms at a measurement location. Stress measurements made using the EPCS and LSP sub-systems are combined to fully characterize the stress properties of a transparent chemically strengthened substrate. Methods of processing the EPCS and LSP measurements and enhanced configurations of the EPCS and LPS sub-systems to improve measurement accuracy are also disclosed.Type: GrantFiled: February 21, 2022Date of Patent: December 26, 2023Assignee: Corning IncorporatedInventors: Ryan Claude Andrews, David Matthew Berg, Pierre Michel Bouzi, William John Furnas, Jacob Immerman, Jeremiah Robert Jacobson, Katherine Anne Lindberg, Glenn Abram Newcomer, Evan Lewis Olson, Viktor Stepanov, Nathaniel David Wetmore

Patent number: 9779190Abstract: Methods for compensating for the warp exhibited by three-dimensional glass covers as a result of ion exchange strengthening are provided. The methods use a computer-implemented model to predict/estimate changes to a target three-dimensional shape for the 3D glass cover as a result of ion exchange strengthening. The model includes the effects of ion exchange through the edge of the 3D glass cover. In an embodiment, the inverse of the predicted/estimated changes is used to produce a compensated (corrected) mold which produces as-molded parts which when subjected to ion exchange strengthening have shapes closer to the target shape than they would have had if the mold had not been compensated (corrected).Type: GrantFiled: February 11, 2016Date of Patent: October 3, 2017Assignee: Corning IncorporatedInventors: Izhar Zahoor Ahmed, Keith Raymond Gaylo, Jacob Immerman, John Richard Ridge, John Robert Saltzer, Jr., Ljerka Ukrainczyk
