Abstract
The theory of coupling model was used to analyze the transmission properties of fiber grating,and matrix method was introduced to simulate the value of the reflection spectrum of uniformity fiber grating.The origin of noise in optical detection was analyzed,and the noise level of laser used in lab was evaluated and validated.By putting different power noise on lamp-house,the influence caused by lamp-house noise on detection of peak value was researched according to the refection spectrum of fiber grating.It was experimented that the demodulation precision of fiber grating was infected greatly by power noise of laser,and the higher the precision of wavelength detected was,the smaller the level of noise should be.When the demodulation precision reached the level of picometer,noise of laser should achieve the high-point of quantum noise.This paper provides theory foundation for the application and research on fiber grating technology used in high precision detecting of weapon equipments.

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 it
