This is the repository for the Abbe Diffraction Experiment. It has two cameras where one captures the Fourier plane and the other acquires the image plane.
This experiment is also a part of the CourseBOX and the detailed alignment tutorial is found here.
- Capture Fourier Plane
- Capture Image Plane
- Low-cost acquisition
- Open-Source
- Compatible with Educational purposes
