Interferometric Instrumentation for Particle Size Analysis

Abstract

This report summarizes the results of a research program conducted to determine the characteristics and potential capabilities of particle size analysis using laser interferometer techniques. Theoretical and experimental analyses are reported which indicate that a range of particle sizes from submicron to millimeters in diameter can be determined when the cross-sectional shape of the particle is known. It is shown that number density can be determined from the interferometric measurements in certain restricted applications. The limitations and potentialities of this method for determining particle size are discussed in detail.
