Routines for analysis of polarization
Project description
A collection of routines to track and visualize polarization through polarizers and birefringent elements. Some ellipsometry support is also included.
There are four numeric modules
pypolar.fresnel - Fresnel reflection and transmission calculations
pypolar.jones - Routines to support the Jones calculus
pypolar.mueller - Routines to support the Mueller calculus
pypolar.ellipsometry - Routines to support ellipsometry
A module for visualization
pypolar.visualization - Routines to support visualization
and three modules that support symbolic algebra
pypolar.sym_fresnel - Symbolic Fresnel reflection and transmission
pypolar.sym_jones - Symbolic Jones calculus
pypolar.sym_mueller - Symbolic Mueller calculus
Detailed documentation is available at Read the Docs.
Installation
Use pip:
pip install pypolar
Usage
Create an optical isolator:
import pypolar.mueller as mueller # Optical Isolator example, no light returning A = mueller.stokes_right_circular() # incident light B = mueller.op_linear_polarizer(np.pi/4) # polarizer at 45° C = mueller.op_quarter_wave_plate(0) # QWP with fast axis horizontal D = mueller.op_mirror() # first surface mirror E = mueller.op_quarter_wave_plate(0) # QWP still has fast axis horizontal F = mueller.op_linear_polarizer(-np.pi/4) # now at -45° because travelling backwards F @ E @ D @ C @ B @ A
