Abstract
Ruby laser holographic interferometry is widely used in engineering measurements even in industrial environments. The pockel-cell of the resonator produces short laser pulses and double-pulses, too. These can be used to study the effect of impacts on examined structures. The only problem is suitable triggering of the laser synchoronized with the impact. As impact generators have been used pendulums, hammers and air guns for example. We have built an impact generator (Fig. 1.) based on the steel bullet coming from the rotational axis of the wheel. The triggering electronics have been built up, too.
