Results are presented for an experimental program which investigated the application of an LDV technique in supersonic flows. This paper presents an analysis of the behavior of light-scattering particles in rapidly accelerating or shock decelerated flows, an evaluation of particle production techniques and the results of several velocity measurements. Measurements included the velocity distribution along the nozzle centerline and flow over a diamond airfoil in a Mach 3 tunnel and velocity profiles for a turbulent boundary layer in a Mach 4.8 facility. It is demonstrated that LDV measurements can be made consistently with errors of less than five percent if the particle lag is considered. (Author).

An introduction to coherent optics and holography is presented. A discussion of the application of lasers in aerodynamics is presented and examples taken from many different laboratories are included. The use of lasers to complement conventional optical methods is reviewed while more advanced techniques are presented in greater detail. These include new methods in interferometry, holography, and laser Doppler techniques.
