Abstract
The diffractive optical element (DOE) is an important component of three-dimensional (3D) imaging systems based on structured light.In this work, we designed the metasurface-driven DOEs based on generalized Rayleigh-Sommerfeld diffraction theory to project large field of view (FOV) pseudo-random dot array for 3D imaging.We measured an efficiency of 61.04% and root-mean-square error (RMSE) of 0.45 for the 60FOV sample and an efficiency of 42.96% and RMSE of 0.75 for the 144FOV sample.Because the pattern is designed based on the generalized Rayleigh-Sommerfeld diffraction theory, the projected pattern is similar to the target pattern and has even intensity.

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
