Abstract

Some years ago we realized that a number of flow velocity measurements we were carrying out using a LDV based on the VISAR principle, could be done faster if instead of measuring the velocity at only one point of the flow field in each experiment, we could measure the instantaneous velocity in the whole plane of interest with only one photograph, called Doppler-picture. The Doppler-picture technique allows the measurement of the velocities of tracers passing through a light sheet that cuts a flow, as well as the measurement of the instantaneous velocity of a fast moving reflecting solid surface.
