[Photonics Research, 2026] Accurate wave propagation modeling with reduced precision

A growable codex of research on neural holography displays.

FFT-DI is a compact Python implementation of the FFT-based direct integration method for the Rayleigh-Sommerfeld diffraction integral. The project is aimed at researchers and engineers who need a readable, modifiable baseline for scalar diffraction propagation rather than a closed optical-design package.
