Zusammenfassung:ABSTRACT During the last two decades, much effort has been put into the remotesensing of atmospheric turbulent layers, using optical devices. The mainscientific interest concerns optical path fluctuations relevant tocommunication and astronomy and the widening of our understanding ofatmospheric physics. Here we describe an original technique that involvesmoving a virtual plane of analysis in the atmosphere. Using this technique,a simple optical combination allows us to explore the atmosphere, wipingout a particular layer while distant layers located beneath or above arereinforced. When combined with the SCIDAR technique, this phenomenon leadsto the "generalized SCIDAR" concept, allowing turbulenceprofiles to be remotely assessed throughout the whole atmosphere, includingthe boundary layer. The potential of this new concept is shown in alaboratory experiment using a vein to simulate an atmospheric turbulentlayer.
