off-axis-holography-python

Description

This repository provides a simple example of holographic reconstruction for images acquired via off-axis holography, and demonstrates how to numerically propagate the optical field.

The workflow includes:

• Retrieving the complex optical field from the recorded hologram
• Performing phase corrections and unwrapping
• Propagating and digitally refocusing the field to arbitrary planes
• Visualizing and analyzing particles in the reconstructed field

Dependencies

• numpy
• matplotlib
• scikit-image
• scipy
• pandas

Examples

Holographic Reconstruction

Start from a holographic image and reconstruct the full complex optical field.

Z-Propagation of Optical Field

Once the optical field is reconstructed, it can be propagated to arbitrary z-planes to simulate refocusing or wave propagation.
