Abstract

In this paper we present a full characterization of a fiber-coupled laser Doppler anemometer, a model describing the different influences of the optical setup, and measurement evaluation on the signal-to-noise ratio model capable of describing the statistical nature of such a measurement system. The characterization is done using a novel method to measure an instrument function of the laser Doppler anemometer: this is performed by reproducibly moving well-defined scattering particles on controlled trajectories through the detection system.
