A differentiable digital twin of a Fraunhofer holographic projector

US & West · 5d

A compact differentiable model of a Fraunhofer holographic projector describes the full propagation chain from a phase-only spatial light modulator to the camera, with physically interpretable parameters. It is identified in situ from hologram-image pairs without extra hardware or system changes, and then used to generate holograms up to the modulator's spatial-bandwidth limit.

Why it matters

Demonstrates building a calibratable digital twin of a physical setup from observed data, an approach transferable to other measurement systems.
