The high speed photography of ballistic experiments by means of a Cranz-Schardin Camera would very often require a multiple time scale spark controller. In the model described hereafter, the digitally adjusted time interval between two successive frames is kept constant within a group of 4 frames, but can be different in the other groups. As an additional feature a Velocity Dependent Delay ensures a precise triggering of the camera. For instance, the first frame can be synchronized with the impact, regardless of the velocity of the projectile.
