Glass Surface Stress Measurement and Digitalization

Abstract:

Surface stress measurement is the key factor of the quality control for tempered glass. The nondestructive test of glass surface stress is based on the character of stress birefringence in glass. The basic principle of the measurement and test methods are introduced. The optical waveguide effect of tin-diffused layers plays a key role in prevalent surface stress measurements. The apparatus are compared for optimizing the testing devices. A portable digitalized surface stress meter based on optical waveguide effect is developed, which can work in severe optical conditions and reduce operation difficulty. The calibration record shows good linearity.
