This paper describes the EMI ruby laser stroboscope and two examples of its application, the study of behind the armor effects of a KE-projectile and the initiation of HE (high explosive) by a hypervelocity debris cloud. The flash x-ray technique is the common method to visualize terminal ballistic and impact phenomena which are mainly combined with light flashes, dust, and fragment clouds. The laser stroboscope is a useful completion to the other techniques, it allows the visualization of long duration (1 ms) events with high-time resolution and high accuracy. At a frequency of 200 kHz, for example, about 260 frames are taken with the camera at exposure times less than 20 ns.
