Description
The polarization of a light beam is the direction of oscillation of its electric field vector. The electric field vector of non-polarized light moves unpredictably and randomly in a plane. If light is required to oscillate in a certain direction, a polarizer is necessary. Linear polarizers make it possible to make the light oscillate in a line through diochrism, birefringence or reflection. If a linear polarizer and a lambda/4 are combined, circularly polarized light is generated, i.e. the electric field vector of the light moves in a circular path.
