Abstract

The concept of linear diffraction tomography is reviewed. Using low coherence tomography as a model we illustrate the importance of gating mechanisms to expand the range of applications, for which linear inverse scattering methods can be used, into the multiple scattering regime. Based on heuristic arguments space-bandwidth product grating (SBPG) is introduced as a generalization of existing gating methods. For turbid media SBPG can be based on geometrical optics and the corresponding phase space representation. First implications to expand the phase space concept to diffractive structures with high permittivity contrast are discussed. Our theoretical investigation is complemented with imaging results originating form numerical simulations.
