A differentiable digital twin of a Fraunhofer holographic projector
US & West ·
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.

arXiv:2610.31864v1 Announce Type: new Abstract: Existing stealthy attacks presuppose white- or grey-box access to the target system, unrealistic in practice. This paper develops a model-free stealthy attack framework that learns an attack policy directly from nominal measurement data, without…
Wireless digital twins (DTs) are increasingly integrated with artificial intelligence to support online modeling, prediction, and network optimization. However, most existing approaches perform adaptation within predefined learning or optimization structures, which may become unsuitable when…
