Abstract
Recent interest in superoscillations has led to theoretical investigations as well as proposed applications in imaging and signal processing. In this paper, we elucidate the relationship between superoscillation and the closely related concept of superdirectivity. Key similarities and differences are highlighted, which showcase windows of possibility for practical superoscil-latory waveform design. Thereafter, through the example of the Optical Super-Microscope - a far-field super-resolution microscope, we demonstrate how established antenna array theory can be leveraged to design a practical superoscillatory filter, which enables far-field sub-diffraction optical imaging. We end by reporting our current progress with the Optical Super-Microscope and suggest future directions to improve its imaging capability.

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
