# Learn computer generated display holography

Here you will find some educational material that might help you to start with computer generated display holography. Details on our real work can be found on the main page. Feel free to ask me any holography-related questions!

## Tutorial course notes

The tutorial **Computer generated display holography** presented at the conference Eurographics 2017, 24 April, Lyon, France.

## Octave/Matlab Holography Tools

**Holography tools** is a set of simple scripts for Octave or Matlab that show actual implementations of some basic building blocks of algorithms used in computer generated display holography. Among others, it contains:

Very basic scripts that generate a hologram; these are basically the same as the scripts for the Eurographics 2017 Tutorial (see above).

Demo scripts that show "advanced" functionality.

Propagation of coherent light between parallel planes using

- convolution in the spatial domain (3x FFT), e.g. the Rayleigh-Sommerfeld integral,
- convolution in the frequency domain (2x FFT), e.g. the angular spectrum decomposition,
- single Fourier transform (1x FFT), e.g. the Fraunhofer approximation.

with optional aliasing control.

Generation of basic waves (spherical, plane).

Basic hologram calculation procedures, e.g. bipolar intensity.

Propagation of a point cloud to a plane with optional aliasing control.
