INO Pyramidal Wavefront Sensor Demonstrator: first closed-loop on-sky operation at Mont-Mégantic Telescope
Bibliographic record
Abstract
Wavefront sensing is one of the key elements of an Adaptive Optics System. As an alternative to the commonlyencountered, commercially available Shack-Hartmann WFS (SH-WFS), the more recent Pyramid-WFS (P-WFS) isproving to be a very attractive technology, thanks to its high-sensitivity and robustness against aliasing. At INO, centerfor applied research in optics and technology transfer in Quebec City, Canada, we have developed a compact andflexible P-WFS prototype that can be integrated into an AO system. This P-WFS prototype includes a fast piezo-electricmodulation mirror and a high-sensitivity EMCCD camera. Our P-WFS was installed on the experimental AO systemdeveloped by Laval University in Quebec for the 1.6-m Mont-Mégantic telescope, which also includes a commercialhigh-speed SH-WFS. The architecture is such that both WFSs can take measurements simultaneously, and either one canbe used to drive the deformable mirror. Here we present the on-sky results obtained with the INO P-WFS module.

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.
