Single- and dual-wavelength monolithic spatial heterodyne spectrometers for Fraunhofer line discrimination spectroscopy
Bibliographic record
Abstract
The background and beginning of this project have been described in a previous SPIE paper1. Since then, the Na monolithic Spatial Heterodyne Spectrometer (SHS) units were constructed, and the housing for the full SHIELDS unit designed and built. The dual-wavelength SHIELDS was designed, and its construction begun, while the LC reflectors used in the selection between wavelengths for the dual-wavelength monolith were tested for efficacy in an instrument-like configuration. Optical modeling and procurement of optical components was completed, making the Na unit nearly ready for lab tests with a low-pressure sodium source, and then appropriate Na-wavelength fluorophores. Atmospheric modeling showed the importance of both dealing with the Ring effect -- as it is at least equal to the fluorescence effect to be measured -- and selecting the best wavelength to observe to mitigate the effects of vegetative fluorescence and water vapor absorption. The full SHIELDS unit has been assembled and initially tested in May 2009, and the dual-wavelength monolith will be completed in July 2009.

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.
