Abstract

Abstract

The digital holographic theories and application in explosion were discussed. The digital hologram of micro-jet from Al flyer with a small conical hole in center under shock load was obtained, based on the questions solved about the resolving power, the dynamic blur, the safety and the accurate time delay synchronization. The micro-jet particles were reconstructed from the hologram in computer. The velocities of micro-jet particles ranged from 2.7 to 4 km/s. And their diameters were from several micrometers to tens of micrometer.
