Python implementation of holographic image reconstruction algorithms

Inline Holographic Reconstruction

Python implementation of Inline holographic reconstruction using the angular spectrum method.

What's inside?

This package includes forward reconstruction of holograms, simulation of holograms using two images as phase and amplitude, and the multi-height phase recovery (MHPR) algorithm to retrieve full object information using a sequence of holograms.

Computations could be performed using two frameworks:

1. Numpy which is suitable for typical applications.
2. Tensorflow which enables GPU or TPU accelerated processing.

Tensorflow also allows embodying the framework in machine learning models.

Outcomes

A Hologram:

Reconstructed Amplitude and phase images by back propagation:

Reconstructed Amplitude and phase images using MHPR method applied on 8 axially displaced holograms:
