Instantaneous, three-component planar Doppler velocimetry using imaging fibre bundles, Experiments in Fluids, Volume 36, Issue 1, pp. 3-10 (2004).0723-4864http://dx.doi.org/10.1007/s00348-003-0586-0http://dspace.lib.cranfield.ac.uk/handle/1826/1129Abstract This paper describes a planar Doppler velocimetry (PDV) technique that is capable of measuring the three, instantaneous and time average components of velocity over two spatial dimensions using a single pair of signal and reference cameras. The three views required to obtain three-component velocity information are guided from the collection optics to a single imaging plane using flexible fibre imaging bundles. These are made up of a coherent array of single fibres and are combined at one end as the input plane to the measurement head. Measurements of the velocity field of a rotating disk are used in the development of the technique and initial results of the instantaneous velocity field of a jet are presented.en-UKArticle
