As a case study, results obtained in Rayleigh-Benard convection experiment are presented. Image processing operations required for the evaluation interferograms and extraction of quantitative data from the optical Images are discussed. Limited-view tomographic algorithms applicable to interferometry are discussed and compared in terms of reconstructed three-dimensional temperature fields. This study concludes that laser interferometry coupled with tomography promises a versatile tool for three-dimensional temperature and flow field measurements in fluids. ER -
