This paper reports a miniaturized device for a spatially distributed characterization of microfluidic two-phase flow, exploiting a multi-wavelength optical signal. The device implements four optical windows (slits) which, superimposed on the centerline of a microfluidic channel, collect flow-related information through specific wavelengths. An advanced polymeric micro-optic design is used to guide and merge spatially distributed information into a single output signal, which maintains memory of the spatial coordinates by using the wavelengths as fingerprints of the slits' positions.

Abstract
This paper reports a miniaturized device for a spatially distributed characterization of microfluidic two-phase flow, exploiting a multi-wavelength optical signal. The device implements four optical windows (slits) which, superimposed on the centerline of a microfluidic channel, collect flow-related information through specific wavelengths. An advanced polymeric micro-optic design is used to guide and merge spatially distributed information into a single output signal, which maintains memory of the spatial coordinates by using the wavelengths as fingerprints of the slits' positions.File in questo prodotto:
