(Opto)mechanical design of the Single Laser Adaptive Optics system for ELT/METIS
Bibliographic record
Abstract
The Mid-infrared ELT Imager and Spectrograph (METIS), which will be one of the first-light instruments on the Extremely Large Telescope (ELT), will be equipped with an Adaptive Optics (AO) system that will use a natural guide star as reference for the correction of the wavefront errors, introduced by the atmospheric turbulence. Even though this system will suffice for the achievement of the instrument’s primary science goals, it will not allow for observations of additional objects of interest, due to the limited sky coverage it offers. In order to increase the sky coverage of the instrument, a supplementary AO system, which will use a single laser guide star as reference, is planned to be added at a later stage. In the present thesis, a possible solution for the (opto)mechanical design of this laser-assisted AO system is provided, which ensures compliance with the predetermined mass, volume and budget limits.

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.
