Abstract: A vehicular rearview assembly, includes a front substrate defining a first surface and a second surface. The front substrate being substantially transparent. The front substrate defines a shaped edge along a periphery of the first surface. A first polarizer is coupled with the second surface. An electro-optic element is coupled to the first polarizer having a first substrate defining a first element surface and a second element surface. A second substrate is spaced away from the first substrate and defines a third element surface and a fourth element surface. An electro-optic material is positioned between the first and second substrates. A second polarizer is coupled to the fourth element surface. A display is configured to emit light having a first polarization into the second polarizer. A reflective layer is positioned between the front substrate and the display is configured to reflect both the first polarization of light and a second polarization of light.

Abstract: A system and corresponding method are disclosed for biometric operations. The system may comprise an illumination source, a polarization selector, an imager, and a controller. The illumination source may illuminate a biometric feature. The polarization selector may receive light reflected from the biometric feature and be operable between two states selectively transmitting different polarizations. The imager may receive the light selectively transmitted by the polarization selector and generate one or more images. The controller may perform a biometric authentication based, at least in part, on the one or more images. In operation, the polarization selector may switch between states so that the system may capture two separate image sets, each based on light of a different polarization. Accordingly, adverse reflections, such as those off an eyeball or glasses, may be substantially eliminated or reduced in at least one of the image sets.
