Abstract
Spectral content in the mid-infrared range is recorded experimentally via a (110)-cut ZnGeP2 electro-optic sampling crystal followed by a ZnGeP2 phase-correction crystal, with the two crystals oriented to exhibit offsetting birefringences on the electric fields associated with the electro-optic sampling process. An enhancement of >13 times is observed in the recorded electro-optic signal (when comparing the electro-optic signals obtained in the presence and absence of the phase-correction crystal). A transfer function embodying this phase-corrected electro-optic sampling approach is derived and subsequently implemented to identify unique spectral features observed in the experimentally recorded electro-optic spectra.

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
