Paper Abstract

Several methods of applying far-field holography to obtain particle size and velocity measurements are discussed. One method involves forming a double exposure hologram of a particle field whereby the reconstructed image is subsequently studied to yield velocity and size information. A similar technique which involves forming a multiple exposure hologram of a particle field is also evaluated. Finally, a method of measuring particle velocities from the optical Fourier transform of a double exposure hologram is analyzed and experimental results for all three cases are presented.
