Abstract

The scattering properties of various particles in relation to particle image (PIV) and speckle (LSV) pulsed laser velocimetry are investigated. Mie's theory for scattering from spherical particles (sizes ranging from 0.05 to 15 microm) is used to evaulate the exposure produced on a photographic plate during a laser pulse. The results are used to determine the minimum particle diameter for particle image operation in water and air for various types of particles (glass or oil particles in air and polystyrene particles in water) and various photographic film properties. From this and information on particle size distribution the minimum necessary particle concentrations for adequate speckle exposure are predicted. The detectability of light scattered from many fine particles or a smaller number of larger particles is compared. The relative advantages and limitations of LSV are discussed.
