In electrodynamics, linear polarization or plane polarization of electromagnetic radiation is a confinement of the electric field vector or magnetic field vector to a given plane along the direction of propagation. The term linear polarization (French: polarisation rectiligne) was coined by Augustin-Jean Fresnel in 1822. [1]
Circular polarization on rubber thread, converted to linear polarization. Polarization (also polarisation) is a property of transverse waves which specifies the geometrical orientation of the oscillations.
Linear polarization was standard into the 1980s and beyond. In the 2000s, computer animation, digital projection, and the use of sophisticated IMAX 70 mm film projectors, have created an opportunity for a new wave of polarized 3D films. [15] In the 2000s, RealD Cinema and MasterImage 3D were introduced, both using circular polarization.
Photon polarization is the quantum mechanical description of the classical polarized sinusoidal plane electromagnetic wave.An individual photon can be described as having right or left circular polarization, or a superposition of the two.
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.
Fresnel's "plane of polarization", traditionally used in optics, is the plane containing the magnetic vectors (B & H) and the wave-normal. Malus's original "plane of polarization" was the plane containing the magnetic vectors and the ray. (In an isotropic medium, θ = 0 and Malus's plane merges with Fresnel's.)
“Polarization means that we are tending toward the extremes rather than toward the center.” The election was so divisive, many American voters went to the polls with a feeling that the opposing candidate was an existential threat to the nation.
The linear polarizer sandwiched between the quarter wave plates is oriented so that it will pass one linear polarization and block the other. The second quarter-wave plate then takes the linearly polarized light that passes and retards the orthogonal component that was not retarded by the previous quarter-wave plate.
