Research output: Contribution to journalArticlepeer-review


This paper is focused on discussing a power modulation-based sensor created using a single-mode optical fiber. The sensing principle allows making displacement measurements with high accuracy and in a large measurement range due to the presence of resonance peaks in the transmitted intensity. A theoretical model is developed for the fiber-optic loop sensor and is validated with experimental data. The results show close matching between theoretical predictions and experimental results, allowing the use of the sensor for displacement measurement.
