Beam Deflection Tomography-Application to Density Measurements in Two Interacting Parallel Free-Jets,
Abstract
Beam-deflection optical tomography is used to reconstruct 2-D density maps in non axisymmetrical media. The images are reconstructed by the convolution backprojection algorithm with M*N deflections measured at M angles and N positions per angle. The reconstruction procedure and the limits of the method are discussed. This technique has been applied to the investigation of the interacting flow between two parallel supersonic free-jets of air or nitrogen. (Author)
