  2. Circular polarization - Wikipedia

    en.wikipedia.org/wiki/Circular_polarization

    Circular polarization is a limiting case of elliptical polarization. The other special case is the easier-to-understand linear polarization . All three terms were coined by Augustin-Jean Fresnel , in a memoir read to the French Academy of Sciences on 9 December 1822.

  3. Stokes parameters - Wikipedia

    en.wikipedia.org/wiki/Stokes_parameters

    The Stokes I, Q, U and V parameters. The Stokes parameters are a set of values that describe the polarization state of electromagnetic radiation.They were defined by George Gabriel Stokes in 1851, [1] [2] as a mathematically convenient alternative to the more common description of incoherent or partially polarized radiation in terms of its total intensity (I), (fractional) degree of ...

  4. 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. Circular birefringence and circular dichroism are the manifestations of optical activity.

  5. Fresnel equations - Wikipedia

    en.wikipedia.org/wiki/Fresnel_equations

    Four weeks before he presented his completed theory of total internal reflection and the rhomb, Fresnel submitted a memoir [30] in which he introduced the needed terms linear polarization, circular polarization, and elliptical polarization, [31] and in which he explained optical rotation as a species of birefringence: linearly-polarized light ...

  6. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    Circular polarization can be created by sending linearly polarized light through a quarter-wave plate oriented at 45° to the linear polarization to create two components of the same amplitude with the required phase shift. The superposition of the original and phase-shifted components causes a rotating electric field vector, which is depicted ...

  7. Elliptical polarization - Wikipedia

    en.wikipedia.org/wiki/Elliptical_polarization

    Circular polarization and linear polarization can be considered to be special cases of elliptical polarization. This terminology was introduced by Augustin-Jean Fresnel in 1822, [1] before the electromagnetic nature of light waves was known. Elliptical polarization diagram

  8. Jones calculus - Wikipedia

    en.wikipedia.org/wiki/Jones_calculus

    In optics, polarized light can be described using the Jones calculus, [1] invented by R. C. Jones in 1941. Polarized light is represented by a Jones vector, and linear optical elements are represented by Jones matrices.

  9. Spin angular momentum of light - Wikipedia

    en.wikipedia.org/wiki/Spin_angular_momentum_of_light

    However, in free space, only two transverse polarizations are allowed. Thus, the photon spin is always only connected to the two circular polarizations. To construct the full quantum spin operator of light, longitudinal polarized photon modes have to be introduced. Left and right circular polarization and their associated angular momenta
