  2. Polarizer - Wikipedia

    en.wikipedia.org/wiki/Polarizer

    Light polarized in the plane is said to be p-polarized, while that polarized perpendicular to it is s-polarized. At a special angle known as Brewster's angle , no p -polarized light is reflected from the surface, thus all reflected light must be s -polarized, with an electric field perpendicular to the plane of incidence.

  3. Polarizing filter (photography) - Wikipedia

    en.wikipedia.org/wiki/Polarizing_filter...

    Circular polarizer/linear analyzer [1] filtering unpolarized light and then circularly polarizing the result. A polarizing filter or polarising filter (see spelling differences) is a filter that is often placed in front of a camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or the sea.

    Mirrored coatings can be made any color by the manufacturer for styling and fashion purposes. The color of the mirrored surface is irrelevant to the color of the lens. For example, a gray lens can have a blue mirror coating, and a brown lens can have a silver coating. Sunglasses of this type are sometimes called mirrorshades. A mirror coating ...

  6. Polarized 3D system - Wikipedia

    en.wikipedia.org/wiki/Polarized_3D_system

    As each filter only passes light which is similarly polarised and blocks the orthogonally polarized light, each eye only sees one of the projected images, and the 3D effect is achieved. Linearly polarised glasses require the viewer to keep his or her head level, as tilting of the viewing filters will cause the images of the left and right ...

  7. Optical rotation - Wikipedia

    en.wikipedia.org/wiki/Optical_rotation

    Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials.
