Definition
Polarization refers to the orientation distribution of the electromagnetic waves that constitute light rays. Light can assume a range of polarization states including unpolarized (uniformly mixed orientations), linearly polarized (fixed orientations), and circularly polarized (rotating field about the line of sight).
Background
The polarization of light is a property that relates to the directionality of the constituent electric and magnetic fields. In free space, light consists of sinusoidally oscillating electric and magnetic fields that are orthogonal to each other and to the direction of propagation. In the case of perfectly linearly polarized light, as shown in Fig. 1, the two types of field remain in a fixed plane through space. For unpolarized light, the orientations of these planes are randomized through temporal and spatial location. Circular and elliptical polarizationsare also...
