Paper Abstract

Intensity diffraction tomography (I-DT) is a non-interferometric imaging method for reconstructing the complex-valued refractive index distribution of a weakly scattering object. The original formulation of I-DT requires measurement of two in-line intensity measurements on parallel detector planes at each tomographic view angle. In this work, a reconstruction theory for multi-spectral is established and investigated for use with single material objects whose dispersion characteristics are known a priori. Unlike other I-DT methods, the temporal frequency of the illuminating plane-wave represents the degree-of-freedom of the imaging system that is varied to acquire two independent intensity measurements on a fixed detector-plane. Moreover, the proposed method accounts for object dispersion.
