Abstract
Higher-order tomographic filters were reported some time back in liter ature, and some results with simulated data were made available. These filters are suitable for the popular convolution backprojection algor ithm used for nondestructive testing (NDT) purposes. This study involv es the application of these filters on some real data. A specimen havi ng a 50-micron structure has been used for the study. The higher-order filters are essentially Fourier-filters. Two-dimensional Fourier-spec trum of the reconstructed images has also been used for studying the p erformance of these filters.
