In-situ measurement of non-steady flows using optical feedback interferometry
Résumé
We present a real-time system for flow measurement in millifluidic configuration based on optical feedback interfero-metry. 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.
