Understanding and controlling the polarization state of light is important
in many optical system applications. Polarizers can be used to evaluate
stresses in objects, modulate and attenuate laser light, investigate molecular
structures or in imaging systems to reduce glare and improve contrast.
CLASSIFICATION OF POLARIZATION
Light is an electromagnetic wave whose electric fi eld oscillates perpendicularly
to the direction of propagation. Light is unpolarized if the direction
of this electric fi eld fl uctuates randomly in time. If the direction of the
electric fi eld of light is well defi ned, it is polarized light.
Linear Polarization - The electric fi eld of linearly polarized light is confi
ned to a single plane along the direction of propagation of the light wave.

Circular Polarization - The electric fi eld of circularly polarized light consists
of two equal amplitude, orthogonal linear components that have a
relative phase diff erence of π/2. The resultant electric fi eld traces a circle
as the wave propagates.
Elliptical Polarization - Results from the combination of two orthogonal
linear components with diff ering amplitudes and/or a relative phase diff erence
that is not π/2. In this case, the resultant electric fi eld traces an ellipse
as the wave propagates.
In order to select a specifi c polarization of light polarizers are used.
Polarizers can be broadly divided into refl ective, dichroic, birefringent,
and thin fi lm polarizers. Linear polarizers are optical elements that are designed
to transmit a specifi c polarization or separate a given polarization
into two orthogonal linear components.
