A survey of the most advanced optical experiments conducted with the help of lasers in the field of mechanics, aerodynamics and ballistics is given: flow visualization, studies of the deformation of materials and structures, vibration analysis, particle sizing and particle velocity analysis, laser velocimetry, shape measurements of 3 D-objects,... All these experiments are related to industrial problems and make use of pulsed lasers and cw-lasers with various techniques such as interferometry, cineholography, optical filtering, fiber optics, light-sheet illumination, etc...
