A technique for measuring the velocity and behavior of particulate suspended in potential and turbulent air flows by means of double-pulsed holography is presented. Descriptions of the air duct facility, particulate dispenser, and holographic systems are provided as well as discussions of experimental results and theoretical considerations. Double-pulsed holography was proved to be an excellent technique for measuring the characteristics of suspended particulate of sizes greater than 6 microns. The measurable characteristics include velocity, three-dimensional coordinates of the particle, size and shape. Specific experiments were performed to determine the feasibility of the double-pulsed holographic technique. These experiments included studies of particulate behavior in electrostatic fields, in potential and turbulent flow, and around a sampling probe for various sampling conditions. (Author)
