Ray theory seismology
WebLater work demonstrated that dynamic ray tracing was in fact a subset of what is called paraxial ray theory in optics, i.e., the study of rays propagating in the vicinity of another ray. This method is new to seismology but it has been used in optics for several decades (see, for example, Deschamps, 1972). Keywords. Gaussian Beam; Synthetic ... WebFeb 13, 2024 · Description.

Web9781560801481. Store. SEG Online Store. The concept of a ray is extremely useful. Rays are curves drawn in space, and they correspond to the directions of flow of propagated energy. In other word, rays are flow lines. Being flow lines, rays cannot cross each other. As such, the ray is a mathematical device rather than a physical entity. Webbuoyancy frequency. In classical ray theory, rays may be regarded as points in phase space moving on the D =0 hypersurface. A significant instance in which standard ray theory fails is in the neighbourhood of ‘avoided crossings’ of different wave modes in physical-wavenumber phase space, where tunnelling between the branches can occur in ...

Seismic Ray Theory … WebA seismic model accepts a description of the subsurface of the earth as input and produces a synthetic seismic record as output. In raypath modeling, ray tracing is carried out for models of multilayered folded structures so as to generate ray diagrams and synthetic time sections.
