[Biomechanical analysis of movement using stroboscopy]

In cases when violence has occurred in some form and its associated forces are subject to expert evaluation. For a mathematical assessment of the intensity of the acting forces there is often a lack of confident basis data, which is why an experimental study is necessary. A simple testing arrangement with a photocamera and flashlight in stroboscopic mode provides a convincing pictorial representation of movement and velocity. The method is described with some examples of applications by experts.
