An optical fiber displacement sensor, based on the light intensity modulation induced by the reflection and/or scattering of a target, is decribed. The optical head is constituted by two GRIN-rod lens ended fibers which make possible the sight of a target within a few millimeter sensing range. A description of the system and the experimental results are presented.
