Fourier Vases

This article delves into Fourier optics, an alternative method for simulating light propagation using Fourier transforms. It contrasts this approach with first-principles FDTD simulations, explaining how Fourier optics efficiently computes wavefield propagation through lenses. The author demonstrates a 4f imaging system using a Shepp-Logan phantom, showing how light diffracts, focuses, and reforms an image. The content includes mathematical derivations, visual animations, and practical insights into optical simulation techniques relevant to computational imaging and physics-based computing.
