ABSTRACT

A Doppler Global Velocimetry (DGV) system based on a cw Argon laser and a single CCD camera has been developed at ISL. In this paper, details of the image processing procedure used to validate this system on a rotating disc are given. The results show a very close agreement between measured and theoretical velocity distributions. An example of measurement on a cross section of a jet flow is also described.
