Abstract

The chirp heterodyne technique allows the directional discrimination of laser Doppler velocity measurements without additional frequency shift elements. This paper presents, for the first time, the use of a chirp-frequency-modulated solid-state-laser, emitting in the green spectral range. The advantage of the chirp heterodyne technique compared to other concepts is, that a single laser source suffices for the directional measurements of multiple component velocities simultaneously. Velocity measurements at two different measurement points are presented.
