Scattered light laser speckle velocimetry for flow field measurement.

This report presents a compilation of the viewgraphs and bibliography prepared for a half day short course on Laser Speckle Velocimetry (LSV) to be presented at the SEM Fall Conference in Indianapolis, Indiana, November 6-9, 1988 LSV is a full field coherent-light technique for the measurement of fluid flows introduced by the authors in the mid-1970's and subsequently developed and applied around the world. In this course comparisons with other familiar coherent optical techniques such as LSP and LDV are used to illustrate the concepts and capabilities of LSV. Fundamental aspects of the LSV technique are presented. These include: seeding, illumination, recording and analysis. Modes of operation (coherent speckle/particle image), exposures (single, double, multiple), sources of noise/ decorrelation and a variety of applications to flow in liquids and gases are also discussed.
