Abstract

We present a real-time system for flow measurement in millifluidic configuration based on optical feedback interferometry. The sensing method exploits the power spectral density information of the acquired signals affected by the backscattered light of particles contained in a fluid. We validate experimentally the method on-site by reconstructing the periodicity of non-steady flows of a peristaltic pump. This demonstrates potential applications for flow assessments in closed liquid-filled circuits.
