| contents | <p>In this study, we introduce a novel migration and inversion framework inspired by path integral formulations in wave physics. Drawing on principles from our companion paper, <em>A Path Integral Formulation of Wave Optics: From Spatial Interference to Temporal Effects</em> (Singh, 2025), we demonstrate the application of path summation concepts to seismic imaging. Our focus is on environments with complex subsurface heterogeneities, including velocity lenses, where traditional ray-based methods struggle. We evaluate migration results across two frequency regimes (25 Hz and 40 Hz) and perform an inversion using a unique phase-based misfit function, optimized in a five-parameter lens model. The results indicate improved resolution, stability, and interpretability of subsurface features, validating the use of coherent path integration in complex media.</p> |
