    Carrier Dependent Stability of a Semiconductor Lattice Measured with Femtosecond X-ray Diffraction

    The melting dynamics of laser excited InSb have been studied with femtosecond x-ray diffraction. These measurements have allowed us to characterize the atomic motion occurring during the initial stages of a ph...

    High-speed visualization, a powerful diagnostic tool for microactuators – retrospect and prospect

     A comprehensive testing of microactuators is decisive (i) to prove the workability, (ii) to characterize the output parameters, (iii) to provide kinematic and temperature data for a revaluation of numerical m...

    The puzzle of whip cracking – uncovered by a correlation of whip-tip kinematics with shock wave emission

    During whip cracking the whip-tip reaches a supersonic velocity for a period of about 1.2 ms, thereby emitting a head wave with a parabolic-shaped geometry. A detailed study of this mechanism which encompasse...

    Flash lighting instrumentation for color schlieren shock wave photography

    Single-shot color schlieren photography of supersonic flow phenomena requires a technically complex flash light source. In particular, it should be of ultrashort duration to minimize motion blur, of high inten...

    August Toepler — The first who visualized shock waves

    The scientific investigation of the nature of shock waves started 130 years ago with the advent of the schlieren method which was developed in the period 1859–1864 by August Toepler. At the very beginning appl...
