Spatially Modulated Fiber Speckle for High-Sensitivity Refractive Index Sensing

Spatially Modulated Fiber Speckle for High-Sensitivity Refractive Index Sensing

A fiber speckle sensor (FSS) based on a tapered multimode fiber (TMMF) has been developed to measure liquid analyte refractive index (RI) in this work. By the lateral and axial offset of input light into TMMF, several high-order modes are excited in TMMF, and the speckle pattern is spatially modulat...
