Infrared radiometry-based background-compensated thermometric instrument for noncontact temperature and friction measurements
Bibliographic record
Abstract
The design and performance of a novel thermometric instrument featuring thermalemission-intensity harmonic modulation, noncontact infrared radiometric detection, and stray background suppression is described. The instrumental principle depends on thermal (blackbody) emission of Planck radiation from a heated surface. It was developed to measure small temperature rises caused by frictional heating. A low-power He–Ne heating laser was used to investigate the sensitivity and estimate a figure-of-merit (FOM) for the instrument. Background compensation leading to signal baseline suppression was partly achieved with a differential mechanical chopper blade, designed to induce destructive interference of infrared radiation superposition from heated and reference spots on a ceramic sample coated with a metallic thin film. Additional background suppression was achieved by lock-in amplifier signal amplitude and phase compensation through an externally superposed wave at the same chopping frequency. The FOM of the noncontact thermometric instrument was 159.9±8.5. The system sensitivity (minimum temperature rise) for the particular thin-film/ceramic material was estimated to be 0.18–0.23 °C.

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.
