Package for polarization state calculations

Project description


Pylarization is a Python module that aids in processing light polarization states. For given method of polarization description it can calculate all parameters of a polarization ellipse.


The following should do, as pylarization does not have any platform-specific dependancies.

pip install pylarization


Polarization Ellipse

PolarizationEllipse is the base class for all classes describing different methods of describing the state of polarization.

To create an instance it is necessary to supply light amplitudes along the X and Y axes and the phase difference between the amplitudes.

light = PolarizationEllipse(0.445, 0.89, 1.57)


Jones Vector

light = JonesVector(0.445, 0.89j)

Stokes Vector

light = StokesVector(1, 0.6, 0, 0.8)


Jonex Matrix

matrix_values = numpy.matrix([[1, 0], [0, -1j]])
light = JonesMatrix(matrix_values) *  JonesVector(1, -1j)
matrix([[ 1.+0.j],

Mueller Matrix

matrix_values = numpy.matrix([[0.5, 0.5, 0, 0], [0.5, 0.5, 0, 0], [0 , 0, 0, 0], [0 , 0, 0, 0]])
light = MuellerMatrix(matrix_values) *  StokesVector(1, 0, 0, 0)
        [0. ],
        [0. ]])

Coherency Matrix

light = CoherencyMatrix(1, 0 ,0 ,0)
