iadpython 0.3.0

'Forward and inverse radiative transport using adding-doubling'

iadpython is a Python module to calculate multiple light scattering (radiative transport) of layered materials. This is a python interface to the inverse adding-doubling package written in C by Scott Prahl. This allows users to extract the intrinisic optical properties of materials from measurements of total reflected and total transmitted light.

The original adding-doubling was developed by van de Hulst to model light propagation through layered media. It was extended to handle Fresnel reflection at boundaries as well as interactions with integrating spheres. Finally, the code was further extended to handle lost light by including Monte Carlo techniques.

Usage

import iadpython as iad

albedo = 0.8 anisotropy = 0.9 optical_thickness = 2.0

UR1, UT1 = iad.

For examples and use cases, see the docs folder on github or view iadpython.readthedocs.com

Installation

First install the iad library

git clone https://github.com/scottprahl/iad.git

cd iad make install-lib

Then install this python module using pip

pip install iadpython

Alternatively you can install from github

git clone https://github.com/scottprahl/iadpython.git

Test by changing the iadpython directory and doing

nosetests iadpython/test_iadpython.py

Then, add the iadpython directory to your PYTHONPATH or somehow
