Quantitative Three-Dimensional Optical Tomographic Imaging of Supersonic Flows

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.
