In order to study and estimate a transient characteristics of an intermittent spray in one shot injection, a novel particle sizer was designed. A detector array of a conventional paricle sizer based on a Fraunhofer diffraction was used and a high- resolution and a time- resolved particle sizer had been made.A time- dependent characteristics of spray in one shot was analyzed.

Keywords：laser Fraunhofer diffraction;intermittent spray;parallel hold
