Abstract : Both reflection holography and transmission holography were applied to investigate the mechanics of bomb detonation and breakup. It was found that transmission holography could be used to acquire information on fragment position, velocity and size distributions. Propelled particles resulting from an explosions were seen using double pulse holographic techniques. Their velocities were calculated from this information. Reflection holography was sucessfully applied to study the surfaces of explosive packages in the act of exploding. The results were related to the theory which predicts image intensity as a function of velocity. The potential and limitations of these holographic techniques are discussed. (Author)
