摘要：

The technology of travel-time tomography, widely used in the fields such as resource exploration and quality testing of construction, is characterized by high resolution, wide detection range, and visual imaging. The technology includes two parts-the estimation of ray tracing and travel time and the rebuilding of images. This paper, based on ray theory, provides forward calculation by using shortest path ray tracing; it also presents fast inversion imaging based on SIRT by comparing different inversions; finally, it provides the stimulation results, and the comparison as well as the analysis of the results proves the validity and practicability of forward calculation and inversion.
