Abstract (EN): A micro-displacement sensing head based on two aligned cleaved fibers inserted into an optical fiber ring and interrogated by an optical time-domain reflectometry is presented. The sensor configuration is characterized for measuring both longitudinal and axial micro-displacements, showing a sensitivity of 0.07 and 2.67 dB/mu m for longitudinal and axial micro-displacements, respectively. A multiplexing system using two of these configurations is also studied.
