pylorenzmie
Python routines for tracking and characterizing colloidal particles with in-line holographic video microscopy (HVM)
Explanation of the module
pylorenzmie
provides a set of python classes for interacting with and
analyzing holographic microscopy data. The hologram of a colloidal
particle encodes comprehensive information about the particle's size,
composition, and location in three dimensions. This package extracts
that information by fitting a recorded hologram to a generative model
based on the Lorenz-Mie theory of light scattering.
Interactive particle tracking and characterization
pylorenzmie
includes a GUI application called LMTool.py
for interacting with experimentally recorded holograms.
