Abstract
We use polarization analysis in triangulation-based laser scanning to disambiguate the true laser stripe from spurious interreflections caus ed by holes and concavities on metal surfaces. Stripe candidates are d iscriminated by projecting linearly polarized laser light onto the obj ects, and measuring the polarization state of the reflected light at e ach pixel of the various candidates. We sketch a model for predicting the polarization state of the true stripe, and report several experime ntal results.
