Talk:Jones calculus

Do we know who Mr. Jones who invented this was? I ask because I suspect it was Isaac Newton's contemporary Sir William Jones and we might as well link to that if so. -- Paul Drye

I'm not sure. --Georg Muntingh

I very much doubt it. Try this:

Jones, R. C., ``New Calculus for the Treatment of Optical Systems I. Description and Discussion of the Calculus, Journal of the Optical Society of America, 31, 488-493 (1941)

The polarizer with azimuth 0:

$P(0)={\begin{pmatrix}1&0\\0&0\\\end{pmatrix}}$

The rotation by $\varphi$:

$R(\varphi )={\begin{pmatrix}\cos \varphi &-\sin \varphi \\\sin \varphi &\cos \varphi \\\end{pmatrix}}$

The polarizer with azimuth $\varphi$:

$P(\varphi )=R(\varphi )P(0)R(-\varphi )={\begin{pmatrix}\cos ^{2}\varphi &\cos \varphi \sin \varphi \\\sin \varphi \cos \varphi &\sin ^{2}\varphi \\\end{pmatrix}}$
