Precise micro flow rate measurements by a laser Doppler velocity profile sensor with time division multiplexing

This paper presents the measurement of flow rate inside a microchannel by using a laser Doppler technique. For this application a novel laser Doppler velocity profile sensor has been developed. Instead of parallel fringe systems, two superposed fan-like fringe systems with opposite gradients are emp...
