Laser-Strophometry: High-Resolution Techniques for Velocity Gradient Measurements in Fluid Flows

This book is the result of two decades of research work which started with an accidental observation. One of my students, Dipl. phys. Volkmar Lenz, - ticed that the speckle pattern of laser light scattered by a cuvette containing diluted milk performed a strange motion every time he came near the cuvette with his thumb. After thinkingabout this effect we came to the conclusion that this motion can only be caused by scatteringparticles with different velocities, as in the case of the diffrac...
