The Application of Holographic Interferometry to the Determination of Discontinuous Three-Dimensional Density Fields.

Abstract

A Fourier transform method is used to invert the integral equation resulting from holographic interferometry of three-dimensional weakly refractive phase objects. The inverted equation is applied to the determination of aerodynamic density fields. The effects of various numerical techniques are extensively evaluated in an attempt to minimize computational effort. Numerical filtering techniques are introduced in order to handle the discontinuities associated with supersonic aerodynamic phenomena.
