Granular stress-optical inverse problem
WebAug 14, 2024 · Having established that a disordered porous material can resemble a granular system, the team investigated the effect of increasing disorder further. They found that as disorder goes up, the strength of a porous material decreases proportionally and may even reach zero if the porosity is high enough. WebMay 1, 2003 · A solution to the inverse scattering problem for diffuse light is obtained in the form of a functional series expansion of the pseudoinverse of the linearized forward-scattering operator and leads to the linear inversion formulas that have been reported previously. We continue our study of the inverse scattering problem for diffuse light. In …
