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 15):
A prism-coupling system for determining at least one characteristic of a part having a bulk refractive index n s , outer surface and a near-surface waveguide region defined by an ion-exchanged region having a peak refractive index n O >n s  and that supports TE and TM waveguide modes:\n a light-source system that generates measurement light; a coupling-prism assembly having a coupling prism with input and output surfaces and a coupling surface that interfaces with the outer surface via an interfacing fluid having a refractive index n f , wherein n p \u2265n f >ns, to define a coupling interface proximate the near-surface waveguide region to couple a portion of the measurement light into the TE and TM waveguide modes and to output a portion of the measurement light from the TE and TM waveguide modes to define TE and TM mode spectra, respectively; a detector system arranged to capture an image of the TE and TM mode spectra; and a controller operably connected to the detector system and configured to processes the captured image to determine the at least one characteristic of the near-surface waveguide region of the part.
