Abstract
A tomographic system which includes a spatial filter suitable to detect phase projections is described. This system is expecting to render 2-D images of slices of transparent object distributions employing well-known tomographic reconstruction techniques for parallel projections. Real and complex spatial filters are considered, including very classical Schlieren filtering techniques, as dark field, Foucault knife-edge, phase-knife edge, phase contrast and others. More recent methods, as fractional methods (fractional derivatives and fractional Hilbert) are also considered. Experimental results using real filters and glass samples are also included.
