Publication number: 20240175812Abstract: A scattered light polarimetry (LSP) sub-system of a hybrid system for characterizing stress in a chemically-strengthened (CS) substrate having a top-surface and a near-surface waveguide, includes a LSP light source system, an LSP light source actuator coupled to the LSP light source system, and an optical compensator within an optical path of a LSP laser beam emitted by the LSP light source system. The optical compensator includes a half-wave plate, a half-wave plate actuator, a diffuser, and a diffuser actuator. The LSP sub-system further includes a LSP detector system in optical communication with the optical compensator through an LSP coupling prism having a LSP coupling surface, a focusing lens and a focusing lens actuator, and a support plenum having a surface and a measurement aperture, the support plenum configured to support the CS substrate at a measurement plane at the measurement aperture, and to operably support the LSP coupling prism.Type: ApplicationFiled: November 28, 2023Publication date: May 30, 2024Inventors: Ryan Claude Andrews, David Matthew Berg, Pierre Michel Bouzi, William John Furnas, Christopher David Gee, Jacob Immerman, Andrew Allen Lindstrand, Glenn Abram Newcomer, Evan Lewis Olson, Melbourne Thompson Turnbull, IV, Nathaniel David Wetmore
