Abstract
Systems and methods for measuring a profile of a glass sample () are disclosed. The method includes scanning a polarization-switched light beam (PS) through the glass sample and a reference block () for different depths into the glass sample to define a transmitted polarization-switched light beam. The method also includes measuring an amount of power in the polarization-switched light beam to form a polarization-switched reference signal (SR), and detecting the transmitted polarization-switched light beam to form a polarization-switched detector signal (SD). The method further includes dividing the polarization-switched detector signal by the polarization-switched reference signal to define a normalized polarization-switched detector signal (SN). Processing the normalized polarization-switched detector signal determines the profile characteristic.
