Hi,

how i could simulate light not yet polarized with jones formalism?

"jones formalism" what is that? Sun light isn't polarized unless its reflected of a surface.

It looks like the best thing you can do is to assume that unpolarized => equally polarized in the x and y (or whatever coordinates you are using) direction. When you say light is unpolarized you are saying that it is randomly distributed. You can always break this down into polarization in x or y direction (assuming the light is traveling in the z direction), and if the light is truly random, there should be roughly 50% of it polarized in the x direction and 50% polarized in the y.

"Note that Jones calculus is only applicable to light that is already fully polarized. Light which is unpolarized, partially polarized, or incoherent must be treated using Mueller calculus."

Guess you can't, it says you must use mueller calculus.

Some of you knows better Mueller calculus?

Having to simulate on PC (with java) the behavior of a photon and polarizers,in your opinion which formalism i could take?
