Principles of Seismic Holography for Diagnostics of the Shallow Subphotosphere

Braun, D. C.; Lindsey, Charles

We develop the wave-mechanical formalism for phase-correlation computational seismic holography of the shallow subphotosphere under the plane-parallel approximation and apply it to helioseismic Doppler observations from the Michelson Doppler Imager on the SOHO spacecraft of both the quiet Sun and active regions. We compare holographic signatures c…
