IMPACT OF THE IMPERFECT POLARIZING-BEAM SPLITTER AND QUARTER-WAVE PLATE AND NON-IDEAL LASER BEAM ON THE ACCURACY OF NANO-DISPLACEMENT LASER ENCODER
Bibliographic record
Abstract
In this paper, periodic nonlinear error of laser encoder for nano-displacement measurement caused by imperfection of polarizing-beam splitter (PBS), quarter-wave plate (QWP), and laser source is modeled by using the Jones matrix analysis. The results reveal that the peak-topeak nonlinearity resulting from imperfect PBS and QWP, and non-orthogonality and ellipticity of the polarized laser beams is obtained as 14.82 nm. Also, considering typical values of transmittance and reflectance coefficients of PBS and different retardation errors of QWP, the first-order and second-order nonlinearities are respectively revealed resulting from imperfect PBS and QWP.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
