Laser Diffraction Particle Analyzer (LDPA) and Phase Doppler Particle Analyzer (PDPA) are generally used for the droplet size measurement. But, their methods are local measurement techniques, which is not suitable for quantitative measurement of the droplet size in a planar cross section. At present, Optical Patternator is applied to measure Sauter mean diameter (SMD) distribution in a cross section of the spray. This method is based on the principles of laser-induced fluorescence (LIF) and Mie scattering (LIS) of droplets in the spray. Relative SMD distributions are obtained through calculating the ratio between two light signals, hi this study, the goal is the quantitative understanding of the planar distribution of droplet size in sprays by Optical Patternator. This research is clarification of the calibration factor using non-dispersion droplets generator. The results of this experiment show that the calibration number has the dependence of the particle diameter.
