Computer Generated Hologram Generation with Scilab (CGH)

Generate CGH and Signal Reconstructions

Generate binary phase masks from black and white images and compute a reconstruction from the phase mask into the signal plane.

Requirements

• Tested with Scilab 2025.0.0 (version 6.1.0 or higher)
• Image Processing and Computer Vision Toolbox (IPCV)

Installation

1. Download and install Scilab from Scilab Official Website.
2. Install the Image Processing and Computer Vision Toolbox (IPCV) dependency via the Scilab console:

   atomsInstall("IPCV")

3. Clone this repository:

   git clone https://github.com/andgdk/cgh.git
   cd cgh

Usage

1. Open Scilab.
2. Navigate to the project directory.
3. Run the main script:

   exec('index.sce');

4. Observe the resulting graphs.
5. Add your own black and white signal images.
6. Update the signal image name variable in index.sce and execute the program.
