Methods of improving the measurement of knee stress in an ion-exchanged chemically strengthened Li-containing glass sample that includes a knee are disclosed. One of the methods includes compensating for a shift in the location of the TIR-PR transition location associated with the critical angle location, wherein the shift is due to the presence of a leaky mode. Another method includes applying select criteria to the captured mode spectra image to ensure a high-quality image is used for the knee stress calculation. Another method combines direct and indirect measurements of the knee stress using the mode spectra from multiple samples to obtain greater accuracy and precision as compared to using either the direct measurement method or the indirect measurement method alone. Quality control methods of forming the glass samples using measured mode spectra and related techniques for ensuring an accurate measurement of the knee stress are also disclosed. 1. A method of measuring knee stress in a chemically strengthened Li-containing glass sample having a warped surface , comprising:capturing a TE mode spectrum and a TM mode spectrum of the glass sample;measuring a TIR-PR slope of light intensity at a TIR-PR transition between a total-internal reflection (TIR) section and a partial-internal reflection (PR) section for one of the TE mode spectrum and TM mode spectrum;measuring a TIR-PR width of the TIR-PR transition for at least one of the TE mode spectrum and TM mode spectrum;comparing the measured TIR-PR slope to a TIR-PR slope threshold and the measured TIR-PR width to a TIR-PR width threshold, wherein the TIR-PR slope threshold and the TIR-PR width threshold are defined by a reference glass sample having a flat surface; andusing the TE mode spectrum and the TM mode spectrum to determine the knee stress if the measured TIR-PR slope is greater than the TIR-PR slope threshold and the measured TIR-PR width is less than the TIR-PR width threshold.2. The method according to ...
