A Dual-Parameter Optical Fiber Sensor for Concurrent Strain and Temperature Measurement: Design, Fabrication, Packaging, and Calibration
Bibliographic record
Abstract
Coupled sensitivity of optical fiber sensors to structural strain and temperature has been a long lasting problem for reliable measurements in environments where both parameters are varying. This problem has been a driving force for the employment of methods to compensate the effect of one parameter. In this paper, a packaged dual-parameter optical fiber Bragg grating (FBG) sensor for the simultaneous measurement of structural strain and temperature using a single FBG is presented. The sensor consists of FBGs with on-fiber silver thin films synthesized by a laser direct write method. The new sensor design, fabrication, packaging, and calibration are addressed. A customized test rig and a sensor calibration package are designed and built. The performance of the sensor for the concurrent measurement of strain and temperature is investigated by analyzing the experimental data, and the characteristic curves for the calibration of the sensor are presented.

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.
