This is a small program that lets one explore Fraunhofer diffraction patterns for light passing through regular polygonal apertures. It can simulate typical apertures used in photographic objectives. Curved sides are approximated by polylines.
Here's how its UI looks:
Several packages are required to build this program.
On Ubuntu 20.04 they can be installed by the following command:
sudo apt install git cmake g++ libglm-dev libqt5opengl5-dev
To fetch and build this program, use the following commands:
git clone https://github.com/10110111/aperture-diffraction.git
cd aperture-diffraction
mkdir build
cd build
cmake ..
make
This will yield an executable called aperdiff, which you can directly run.
