Fourier Optics Demos and Tutorials
These demos are intended to be a gentle introduction to several fundamental Fourier optics concepts/techniques. These tutorials draw heavily upon Matlab code from Laura Waller's Open Source Matlab Code.
More tutorials coming soon!
Tutorials
1. Digital Holography (Notebook)
Digital refocusing of amplitude targets using Fresnel propagator. Two modes:
- simulated: propagates complex field by a desired distance
- experimental: takes in defocused image from microscope and propagates to digitally refocus the image
2. Quantitative Phase from defocus (Notebook)
Takes in a defocused image stack and solves for the phase of the object using Gerchberg-Saxton.
