Stokes Parameters Computation

This example demonstrates the computation and visualization of the Stokes parameters using PyMieSim.

Importing the package: PyMieSim

from PyMieSim.single.scatterer import Sphere
from PyMieSim.single.source import Gaussian

Defining the source

source = Gaussian(
    wavelength=750e-9,  # 750 nm
    polarization_value='right',  # Right circular polarization
    polarization_type='circular',
    optical_power=1,  # Arbitrary units
    NA=0.3  # Numerical Aperture
)

Defining the scatterer

scatterer = Sphere(
    diameter=300e-9,  # 300 nm
    source=source,
    index=1.4  # Refractive index of the scatterer
)

Computing the data

data = scatterer.get_stokes(sampling=100)  # Specify the number of sampling points

Plotting the data

figure = data.plot()

Display the plot

_ = figure.show()
