Abstract

A miniature sized instrument called the 3D micro laser Doppler anemometer was developed at the Cranfield Institute of Technology, U.K., primarily intended for boundary layer measurements in centrifugal compressors but retaining all the features of other conventional laser Doppler anemometers. It has a high spatial resolution and uses oblique back scatter to enable velocity measurements in all three dimensions. An optical head is remotely connected via fibre optic cables to the laser, photomultiplier tubes and signal processing equipment. The design objectives, design philosophy and commissioning of the instrument are described. The mathematics of these dimensional measurements and the results of a test to demonstrate the instrument are also presented.
