Abstract:
Prism coupling systems and methods for characterizing curved parts are disclosed. A coupling surface of a coupling prism is interfaced to the curved outer surface of the curved part to define a coupling interface. Measurement light is directed through the coupling prism and to the interface, wherein the measurement light has a width of 3 mm or less. TE and TM mode spectra reflected from the interface are digitally captured. These mode spectra are processed to determine at least one characteristic of the curved part, such as the stress profile, compressive stress, depth of layer, refractive index profile and birefringence.

Claim (Index 11):
A method for determining at least one characteristic of a part having a bulk refractive index n s , an outer surface and a near-surface waveguide region defined by an ion-exchanged region having compressive stress and a peak refractive index n O >n s , comprising:\n supplying light to the near-surface waveguide region through a coupling prism of refractive index n p  and through an interfacing fluid of refractive index n f  disposed between the coupling prism and the outer surface to cause the light to travel in the near-surface waveguide region as TE and TM guided waves, and where n p \u2265n f >n s ; extracting the light of the TE and TM guided waves from the near-surface waveguide region though the interfacing fluid and the coupling prism, wherein the extracted light includes a TE component that defines a TE mode spectrum having TE mode lines and a TM component that defines a TM mode spectrum having TM mode lines; capturing an image of the TE and TM mode spectra; measuring relative positions of the TE mode lines and the TM mode lines using the captured image; and using the measured relative positions of the TE mode lines and the TM mode lines to determine a least one characteristic of the near-surface waveguide region of the part.
