Abstract
A technique is presented that enables the particle-size analysis of quasicircular particles to be made. A coherent optical system is used to generate the diffraction pattern of the particle population to be analyzed, and a digital computer is used to process the information in the pattern. A similar technique has been used earlier, with success, to count circular particles of varying diameters. A scene containing three classes of particles is analyzed, and results are furnished.Keywords
