A method for improving illumination analysis in seismic data having steps of: selecting a model of the medium, a source and a receiver, a reflecting surface, finding a reflection point and the associated Fresnel zone according to Fermat principle using ray tracing, calculating the illumination in the Fresnel zone using the wave equation, repeating the illumination calculation for all frequencies all points on the reflecting surface and all source and the receiver pairs. The resulting illumination image may be used to assess the quality of or improve the seismic image of the same medium. |
