A compact, reduced-cost optical fibre sensor is presented for the combined measurement of the size, density, and relative refractive index of monodispersive particulates. The sensor uses multimode optical fibres and GRIN rods to analyse scattering and absorption at multiple wavelengths and detection angles. The particle size, density and refractive index values were obtained through calibration.

Abstract
A compact, reduced-cost optical fibre sensor is presented for the combined measurement of the size, density, and relative refractive index of monodispersive particulates. The sensor uses multimode optical fibres and GRIN rods to analyse scattering and absorption at multiple wavelengths and detection angles. The particle size, density and refractive index values were obtained through calibration.File in questo prodotto:
