Resumen/Abstract
In this work, a fabrication technique for microchannel-based reflectors used as an optical fiber sensor is demonstrated by using a processed optical fiber by an ultrafast laser-assisted etching method. 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.
