Abstract
We present a novel fluid-velocimetry technique based on speckle interferome try. The light scattered from an illuminated plane is recorded with a CCD c amera at the same time as a speckled reference beam. Substraction of two no nsimultaneous frames provides information about the velocity field for an o ut-of-plane component. An application to a Rayleigh-Benard convective flow is given.
