Holographic measurement of microparticle velocities
Abstract
Double exposure techniques in GABOR setup are used for microparticle velocity measurement. Experiments were performed with particles suspended in an air flow of 100 m/s velocity. Results are in agreement with computer based forecasts. The measurement quality and technical limitations are evaluated; proposals for improvement are presented.
