Droplet size measurements by laser interferometry
Abstract
The theoretical background for the use of laser Doppler anemometry to measure fuel droplet size is set forth. The problem is the calculation of the scattered field arising when a particle is illuminated by two beams of monochromatic coherent radiation. The construction of visibility-diameter curves for different values of the experimental parameters is explained. The method is practical up to particle diameters of 100 microns.
