Abstract
Summary
In case of a broken hologram, an image of the complete object can still be obtained from one of the fragments. The reason is that each diffraction point of the object sends out waves that reach every point on the hologram. As an analogy, we propose to separate diffractions from standard seismic reflection data. The use of a decimated version of such data (violating the Nyquist sample condition) should still contain all necessary information to obtain an image of the finer details of the subsurface employing the concept of holographic migration. The feasibility of the proposed approach is supported by a field data example from the Barents Sea.
