Abstract: A method for determining crystal phases of a glass ceramic sample, including the steps of applying energy to the sample using an excitation source, detecting raw Raman spectral energy that is given off by the sample using a detector, wherein the raw Raman spectral energy includes peak values, determining a plurality of predetermined energy peaks based off a composition of the sample, superimposing the plurality of predetermined energy peaks over the raw Raman spectral energy, applying a baseline value between each predetermined energy peak, subtracting the baseline value from the raw Raman spectral energy, calculating corrected peak values based on the raw Raman spectral energy and baseline value, and determining the crystal phases of the glass ceramic sample based on the corrected peak values.

Abstract: An apparatus for testing the edge strength of a discrete sheet of material such as glass where the sheet has an irregular free-form shaped outline is disclosed. The apparatus can include a plurality of assemblies configured for selectively applying a 3-point bending load on an edge of the sheet of material in a test region of the apparatus, a detection mechanism that optically measures strain in the sheet of material in the region, and a processor that determines the stress in the sheet based on the measured strain by calculating the stress that would be required to produce the measured strain in the sheet of material.

Abstract: Apparatus and method for testing a sheet of brittle material comprising the steps of measuring one or more edge features of a sheet of brittle material, imparting a bend to the sheet of brittle material and producing relative motion between the sheet and the bend such that the bend traverses the sheet. A stress can be induced in the sheet as a function of the relative motion and imparted bend, wherein the induced stress corresponds to a predetermined strength value, and the measured one or more edge features can be correlated with the strength value.

Abstract: A method includes introducing light into a glass article such that at least a portion of the introduced light is emitted from an edge of the glass article. The light emitted from an edge of the glass article is detected. An intensity profile of the emitted light is an intensity of the emitted light as a function of axial position. A first intensity boundary of the intensity profile and a second intensity boundary of the intensity profile are determined. A thickness of a layer of the glass article is determined based on an axial distance between the first intensity boundary and the second intensity boundary.
