Abstract

Electronic speckle pattern interferometry in the transmission mode is shown to be an efficient tool for visualizing the thermal distribution in a transparent liquid. Examples of the Rayleigh Bénard convection pattern are determined. The position of the ground glass with respect to the liquid volume is discussed, and the capacity to combine streamlines and temperature field measurements within the same optical setup is established.
