Abstract

An application of the multiple-exposure speckle photography to the Rayleigh-Benard flow is described. A fluid seeded with a minute concentration of diffusing particles is illuminated by a laser light sheet. The multiple-exposure photograph of this sheet is analysed by the well-known techniques of speckle photography to obtain a bidimensional map of the instantaneous velocities.
