Quantitative Three-Dimensional Optical Tomographic Imaging of Supersonic Flows

GREGORY W. FARIS 1 and ROBERT L. BYER 1

1 Edward L. Ginzton Laboratory of Physics, Stanford University, Stanford, CA 94305.

Three-dimensional imaging of the density of nitrogen in a supersonic expansion from a nozzle by means of beam-deflection optical tomography is described. With a very simple apparatus, images could be obtained with high absolute accuracy, high spatial resolution, and wide dynamic range.
