Abstract: An optical sensor module uses polarized light such that, in some instances, crosstalk effects caused by light reflected from a cover glass or from a thin smudge layer on the cover glass can be eliminated, or at least reduced, by directing light of a first polarization through the cover glass toward a target and selectively detecting, in the module, light of a second polarization that is orthogonal to the first polarization.
