Highly Sensitive Photoacoustic Imaging: A New Strategy for Ultrahigh Spatial Resolution Seismic Physical Model Imaging
Published 2020-01-01Get full textSeismic-physical-model imaging (SPM), a successful strategy for the research in seismic wave propagation and wave theoretical predictions, effectively bridges the computation modeling and the field exploration and leads to a nearly ideal setting without a rock matrix. However, the current strategy f...
