Time-shift imaging condition in seismic migration |

To be even more general, we can formulate an imaging condition
involving both space-shift and time-shift,
followed by image extraction at zero time:

However, the cost involved in this transformation is large, so this general form does not have immediate practical value. Imaging conditions described by equations (3)-(4) and (6)-(7) are special cases of equations (9)-(10) for and , respectively.
