Abstract

fetched live from OpenAlex

Abstract A phase shifting Twymann-Green interferometer for the measurement of plane angle has been developed and characterized using a small-angle generator directly traceable to the definition of the radian. The impact of surface form on the measured angle was explored using a simple deformable mirror. The angle sensitivity of the interferometer did not depend upon the surface form. Comparison of the calibrations of two polygons and two angle gauge blocks by both the angle interferometer and a commercial autocollimator showed excellent agreement with normalized errors of less than 0.4. The standard uncertainty for the angle interferometer when measuring the polygons was less than 0.02.

Teacher imitation

Not 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.
