The size distribution of small praticles can be obtained by optical analysis of the Fraunhofer diffraction light scattered by particles. In this study, direct photographs of the diffracted light from particles or spray drops were taken using a pulsed laser and analyzed. Error due to the characteristic properties of this pulsed laser diffraction method were investigated for many groups of particles. The mean particle size was measured within an error of less than ±10%, even if the diffmacted light from particles passed through a high ambient temperature and pressure envirnment. The Fraunhofer diffraction pattern of a diesel spray in a vaporizing process was analyzed by this method to obtain the Sauter mean diameter of the spray.
