Abstract
This paper describes the analysis of holographic interferograms of turbulent flowfields, obtained from hypersonic shock tunnel evaluation tests of cooled, aero-optic window designs. Three different fringe analysis techniques -- phase shifting, spatial Fourier transform, and fringe tracking -- are compared and contrasted.
