Sažetak
New mathematical techniques have contributed substantially to the improvement of the geophysical prospecting methods, like traveltime seismic tomography. Thanks to these new techniques, the time to solve an inverse problem has been reduced dramatically making seismic tomography applicable to a great number of problems even in three dimensions. New raytracing and wavefront techniques provide a more flexible parameterization. Advancement from the least squares technique to today’s back-projection method’s, for example, has improved tomographic methods.
