Point spread function reconstruction from Woofer-Tweeter adaptive optics bench
Bibliographic record
Abstract
This paper describes a model-based and experimental evaluation of a point spread function (PSF) reconstruction technique for a Dual Deformable Mirror (DM) Woofer-Tweeter (W/T) Adaptive Optics (AO) system. In the W/T architecture, the Woofer is a low-order-high-stroke DM, and it is used to compensate for the low-frequency-high-amplitude effects introduced by the atmospheric turbulence. The Tweeter is a high-order-low-stroke DM that is used to compensate for the high-frequency-low-amplitude effects introduced by the atmospheric turbulence. The research concept of having Dual DMs allows the W/T AO system to have a high degree of correction of large amplitude wavefront distortion. The role of the UVic AO bench is to demonstrate the closed-loop wavefront control feasibility for a W/T AO concept to be used on the science instruments of the Thirty Meter Telescope (TMT).

How this classification was reachedexpand
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.
