A novel approach for fiber optics 3D shape sensing, applicable to mini-invasive bio-medical devices, is presented. The approach exploits the optical backscatter reflectometry (OBR) and an innovative setup that permits the simultaneous spatial multiplexing of an optical fibers parallel. The result is achieved by means of a custom-made enhanced...

We introduce a novel multiplexing technique applied to optical fiber distributed sensors, based on optical backscatter re-flectometry (OBR) and high-scattering MgO-doped fibers. In this paper, we demonstrate the possibility of simultaneously detecting multiple fiber with a single scan using an OBR distributed sensor, and successfully...
Featured Application: Inscription and interrogation of fiber Bragg gratings into MgO nanoparticle-doped fiber for optical fiber distributed and multiplexed sensing. Abstract: The characterization of Fiber Bragg Grating (FBG) sensors on a high-scattering fiber, having the core doped with MgO nanoparticles for polarization-dependent temperature...

The high demand in effective and minimally invasive cancer treatments, namely thermal ablation, leads to the demand for real-time multi-dimensional thermometry to evaluate the treatment effectiveness, which can be also assisted by the use of nanoparticles. We report the results of 20-nm gold and magnetic iron oxide nanoparticles-assisted laser...

Optical Backscatter Reflectometer (Luna OBR 4600 ) can transform a single mode fiber SMF in an efficient spatially distributed sensor of temperature and strain Unfortunately, t he operation field of OBR is limited to a single sensing fiber element . A parallel of multiple fibers is problematic as t he back scatter ed power to disc rimi nate is...
