Beam-deflection optical tomography
Abstract
Two-dimensional density measurements in a supersonic expansion using beam-deflection optical tomography are reported. Quantitative, high-resolution images with absolute accuracy to 3.5 percent and spatial resolution to 50 microns were taken with a helium-neon laser and simple apparatus.
