Hedlund	Measurement of Flow Perturbations Occurring Both Naturally and by Plasma Induction over a Mach 4.5 Corner Separation Zone	1904		.txt	text/plain	330	13	39	Three measurement methods were used to determine the frequency spectrum of flow perturbations: a high-frequency Shack-Hartmann wavefront sensor, a laser differential interferometer, and high-frequency pressure sensors. Flow visualization was provided by a schlieren imaging system and planar laser Rayleigh scattering (PLRS) to characterize the flow structure with various Rel.	cache/d791sf2933j.txt	txt/d791sf2933j.txt
