Abstract

A modified iterative conjugate gradient technique is developed and applied to limited-view interferometric tomography for reconstructing flow fields of simple structure. The approach is also effective in dealing with significant noise present in the data. From a computer simulation of experiments, a multipath interferometric system is built, from which multidirectional projection interferograms can be captured in real time for fast transient phenomena. The system is employed to measure an asymmetric temperature field. The three-dimensional field is then reconstructed with the developed experimental and computational techniques. The results are satisfactory when compared with thermocouple measurements.
