- Abstract:
- We report about a novel laser Doppler field sensor, which is capable of measuring the three-component (3C) velocity field in fluid flows in a twodimensional area (2D) without mechanical scanning and without using a camera. The sensor is based on laser Doppler velocimetry but employs four superposed fan-like interference fringe systems. A spatial resolution in the sub-micrometer range can be achieved enabling highly spatially resolved flow studies. Possible applications are investigations in micro-fluidics or precision flux measurements.
