Abstract
Super-oscillatory (SO) imaging is a far-field imaging technique to super-resolve unlabeled objects. Previous theoretical and simulation-based studies have shown attractive possibilities to simplify the SO imaging configuration by implementing SO imaging numerically. However, numerical SO imaging has not yet been experimentally demonstrated in real optical systems. In this work, we reconstruct the complex field of a diffraction-limited (DL) image with the phase-shifting interferometry (PSI) technique, enabling the application of numerically designed SO filters in the Fourier domain. Experimental results at a wavelength of 632.8 nm validate the proposed method, showing improved resolution and image fidelity. Quantitatively, the full-width-at-half-maximum (FWHM) is reduced by 42% and the structural similarity index (SSIM) is enhanced from 0.19 to 0.29.

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
