Optical diffraction tomography using conjugate symmetry
Abstract
The fidelity of reconstruction in 3D optical diffraction tomography is often limited by missing directions of illumination, which create gaps in the accessible Fourier space. If the object function is real, then even conjugate symmetry (CS) can be used to fill in such gaps. However, in general, the object function is complex, and therefore, CS is not applicable. Nevertheless, we show that, in the Born approximation and for weakly scattering objects, when either the real or the imaginary components of the refractive index contrast between the object and the background dominate, then use of either even or odd CS can enhance the fidelity of linear tomographic reconstruction.
