Abstract

Interferometric optical tomography is a valuable method for combustion and flow diagnostics. However, it meets serious experimental difficulties when investigated objects are large (about 50 sm or greater) and/or perturbations of refractive index are greater than 0.01. In the latter case the interference fringes become too thin, while in the former case too large and expensive optical elements (lenses and holograms) are required. These difficulties can be overcome by using optical ray-deflection tomography with fan-shaped beams. In the paper a scheme of the tomographic experiment, reconstruction algorithms, and experimental results are presented.
