Folding-up of the vertical atmospheric turbulence profile using an optical technique of movable observing plane

Up to now, most of optical techniques of vertical turbulence profiling were based on the analysis of the scintillation produced at the ground level, preventing from low altitude layer detection. A simple optical combination allows us to explore the atmosphere, wiping out a particular layer while remote layers located beneath or above, are reinforced. A laboratory experiment which involves an optical bench and a simulated turbulent layer is described, and shows the potentialities of the new concept.
