Abstract

Les véhicules, notamment automobiles, sont pourvus, en plus des phares habituels 12, de phares spéciaux 13 émettant, grâce à l'interposition d'un filtre polarisant une lumière polarisée de forte puissance. Les pare-brise 14 et/ou lunette arrière 15 et/ou rétroviseur 16 des véhicules sont également pourvus d'un filtre polarisant dont l'axe de polarisation fait un angle alpha avec l'axe du précédent filtre. Il s'ensuit que, lorsque deux véhicules V et V' de ce type se croisent, leurs occupants ne perçoivent que peu ou pratiquement pas (selon la valeur alpha ) la lumière polarisée.
