摘要：

We use polarization analysis in triangulation-based laser scanning to disambiguate the true laser stripe from spurious interreflections caused by holes and concavities on metal surfaces. Stripe candidates are discriminated by projecting linearly polarized laser light onto the objects, and measuring the polarization state of the reflected light at each pixel of the various candidates. We sketch a model for predicting the polarization state of the true stripe, and report several experimental results.
