Abstract

fetched live from OpenAlex

The Adaptive Optics Laboratory of the University of Victoria has build a LGS SH-WFS test bench for the Thirty-Meter-Telescope project and its AO system, NFIRAOS. The UVic AOLab has recently shown the ability to track Na profile induced aberrations while correcting for turbulence aberrations. The UVic AOLab has started the second phase of development of its LGS SH-WFS test bench. This next step consists in adding the Truth WFSs into the current bench design and in modeling and implementing the algorithms which blends the data coming from the variousWFSs. This paper shows the various components of the control architecture of NFIRAOS LGS wavefront sensing process. A first simulation shows the stability of the proposed control architecture and demonstrates that the DM is kept away from reproducing the LGS aberrations.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
