A collection of routines to track and analyze laser speckle. This is a python port of SimSpeckle Matlab routines described in Duncan & Kirkpatrick, “Algorithms for simulation of speckle (laser and otherwise),” in SPIE Vol. 6855 (2008)

This implementation contains code for

  • 1D exponential and gaussian speckle

  • 2D speckle algorithms

  • 3D speckle generation

Documentation and examples are available at <>

Using pyspeckle

  1. Install with pip:

    pip install pyspeckle
  2. or run this code in the cloud using Google Collaboratory by selecting the Jupyter notebook that interests you.

  3. use binder which will create a new environment that allows you to run Jupyter notebooks. This takes a bit longer to start, but it automatically installs pyspeckle.

  4. clone the pyspeckle github repository and then add the repository to your PYTHONPATH environment variable
