This microdisplacement sensor was experimentally demonstrated to hace an outstanding resolution of 5.9 rad/mp in the measurement range from 0 to 80 microns, by using the fast Fourier transform (FFT) measuring method.}, organization = {This work was supported in part by projects PID2022-137269OB, funded by MCIN/AEI/10.13039/501100011033 and FEDER “A way to make Europe”, and TED2021-130378B funded by MCIN/AEI/10.13039/501100011033 and European Union “Next generation EU”/PRTR, and by the R+D project INNVAL23/10 financed by IDIVAL.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2025, 13639, 1363966}, publisher = {29th International Conference on Optical Fiber Sensors, Porto, Portugal, 2025}, title = {Microdisplacement sensor based on a processed optical fiber by an ultrafast laser-assisted etching method}, author = {Pérez Herrera, Rosa Ana and Roldán Varona, Pablo and Sánchez González, Arturo and Goméz Galdós, Celia and López-Amo Sainz, Manuel and López Higuera, José Miguel and Rodríguez Cobo, Luis}, }
