Abstract
Computer-generated holography offers a promising route to three-dimensional (3D) video displays. To realize a realistic-looking 3D display, the critical challenge is to create a 3D hologram that enables high-density multi-plane projection with full depth control. However, two long-existing issues in current digital holographic techniques, low axial resolution and high inter-plane crosstalk, prevent fine depth control and therefore limit the ultimate quality. Here, we report 3D scattering-assisted dynamic holography (3D-SDH) that further breaks the depth-control limit of the state-of-the-art method. Our approach achieves orders of magnitude improvement in axial resolution and greatly suppresses crosstalk, enabling ultrahigh-density 3D holographic projection. Moreover, 3D-SDH enables dynamic 3D vectorial projections via phase-only holograms. The concept is validated through both simulations and experiments, where dynamic projections of 3D point-cloud objects onto high-density successive planes are demonstrated. Our work opens perspectives for 3D holographic technology with ultra-fine depth control, dynamic projection, and polarization multiplexing functionalities.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
