Stokes parameters A tiny itsy-bitsy little bit of history .

Stokes parameters A tiny itsy-bitsy little bit of history .

1669: Bartholinus discovers double refraction in calcite

17th – 19th centuries: Huygens, Malus, Brewster, Biot, Fresnel and Arago, Nicol .

19th century: unsuccessful attempts to describe unpolarized light in terms of amplitudes

1852: Sir George Gabriel Stokes took a very different approach and discovered that polarization can be described in terms of observables using an experimental definition

Part II: Stokes parameters

Slide 20

Stokes parameters (I)

Stokes parameters (I)

The polarization ellipse is only valid at a given instant of time (function of time):

To get the Stokes parameters, do a time average (integral over time) and a little bit of algebra .

Part II: Stokes parameters

Slide 21

Stokes parameters (II) described in terms of the electric field

Stokes parameters (II) described in terms of the electric field

The 4 Stokes parameters are:
