Abstract
Three-dimensional position and velocity information can be extracted by directly analyzing the interference patterns of in-line, Fraunhofer holograms of small spherical particles. Spherically diverging light is shown to enhance resolution accuracy of the components of displacement perpendicular to the film plane. Data are obtained by measuring the radii of the interference patterns. The theory, experimental verification, and error analysis of this basic problem are discussed.Keywords
