Unpolarised light, stokes vector and image matrices.

[RacerX]

I was working on a project of image encryption and I got stuck at something.

I'll go point-wise.

1. I need to make optical element filters like linear polariser, circular polariser, retardets etc. working in matlab.
2. I decided to use mueller calculus and stokes vectors.

So, I would use the stokes vector for unpolarised light and multiply with it an image matrix to get the image information,...this would be the incident beam on the optical element.

and then, apply mueller matrices to get the desired results.

Now, because stokes vectors are of [4*1] size and images are of arbit matrix sizes, they can't go multiplication.
for eg. (4x1)*(256x256) ??

and further mueller matrices can't be operated either.

Is there any work around to this?
or Am I doing something wrong above?
Please help.

Thanks

The issue you are running into is that the Stokes vector can only be applied to a single pixel at a time, so you would need to iterate it over every pixel in the image matrix. To apply Mueller matrices to the image matrix, you will need to first convert the image matrix into a vector of Stokes parameters, then apply the Mueller matrices to the vector, and then convert the vector back into an image matrix. This process should allow you to apply Mueller matrices to your image matrix.
