Transfer-Function Approach to Substrate-Enhanced Diffraction Tomography

arXiv:2509.20676v1 Announce Type: new
Abstract: Forward and backward scattering provide complementary volumetric and interfacial information, yet conventional three-dimensional (3D) imaging typically accesses only one. In this Letter, we present a substrate-enhanced diffraction tomography approach that simultaneously recovers both channels under multi-angle epi-illumination.
