Abstract

Laser Doppler anemometry is a well known technique for non-invasively measuring fluid flow. Originally developed using gas lasers, the inclusion of semiconductor laser diodes and detectors [1] and optical fibres [2] have made it possible to construct compact and robust probes. To extend laser Doppler anemometry to multi-component velocity measurements, some method of distinguishing the various velocity components is essential.
