Three-dimensional measurement of the droplet size in a fuel spray was performed using a pulsed laser holographic method in order to study the spray characteristics. The holographic interferometric image of the fuel spray was recorded on the holographic plate using a pulsed Nd:YAG laser. The three dimensional images of the spray droplets were reconstructed using a continuous wave Nd:YAG lser and were observed by a microscope CCD camera. To measure the size and the location of the reconstructed spray droplets in a short period of time, an automatic measurement system was developed. The spatial distribution of the droplet size was obtained within 10 minutes by analyzing the reconstructed image with this system. The measurement system was applied to the spray injected by a D.I. gasoline injector.
