Abstract

Using the recently developed Fraunhofer plane particle size analyzer, comparisons have been made between direct and holographically recorded particle field measurements. The usefulness of the combination is discussed in terms of the considerable time factor gain in hologram analysis and the improvement in time resolution of the instrument to that of pulsed lasers. The time resolution is demonstrated by the observation of the time development of the particle size distribution associated with a fuel injector during and after the few milliseconds of nozzle opening.
