pypolar 0.7.0

Routines for analysis of polarization

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
