Abstract

Based on the principle of "freezing" high-velocity particles,an in-line Fraunhofer far-field holography measurment system,which uses the ultra-short pulse laser as the recording light source,is constructed.The metal micro-jet is loaded by detonation.The hologram of micro-jet is obtained by this system.By reconstructing the hologram,the distribution and the size of the micro jet can be analyzed.
- pulse holography,
- the information of the particles field,
- recording and reconstruction,
- micro-jet
