Abstract

During the last 30 years, Laser Tomography and the use of Light Scattering for flow characterization have known numerous improvements and variants, summarized in this paper. We describe the standard illumination systems and note that the usual term “plane laser sheet” is in fact ill advised: real laser sheets  are complex light distributions, whose energy profiles can be calculated only if the emission modes of the illumination laser are known. We also detail the paradoxical limitations of the tomographic analysis: how to use a strictly 2D technique (plane sheets) for 3D investigations? A partial solution is the control of the sheet shape and the knowledge of the true sheet thickness. In order to obtain real 3D informations, qualitative or quantitative, various ways are examined : sequential tomography, two or multi-plane tomography with polarizing or wavelength coding, volume illumination by means of oscillating sheets or XY beam sweeps and finally the specific 3D Rainbow Velocimetry approach. We conclude by a short presentation of the recent tendencies.
