New generation of Fabry-Perot fiber optic sensors for monitoring of structures
Bibliographic record
Abstract
This paper reports on a new generation of Fabry-Perot fiber optic sensors to be used in parallel or in replacement of conventional instruments for monitoring of structures. The new generation of sensors is based on a unique fiber optic strain sensor that represents a breakthrough in fiber optic sensing. The novel technique is based on extrinsic Fabry-Perot white- light interferometry which offers outstanding accuracy and repeatability. Furthermore, all sensors are completely immune to lightning surcharges which opens new possibilities in the field of reliable long term structure monitoring. Instruments such as piezometers, embedment strain gages, surface strain gages, temperature sensors and displacement transducers are all available in Fabry-Perot fiber optic version. Furthermore, all these instruments use a common multimode optical fiber to carry the signal to the readout units and multi-channels dataloggers. Both static and dynamic measurements are possible with this technology. The paper presents results of laboratory and field studies on fiber optic sensors mentioned above including integrated fiber optic sensors in carbon and glass fiber reinforced polymer. A case study of bridge strain monitoring with Fabry-Perot sensors is also reported.

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.
