Abstract
The paper gives a review of interferometric and photoelastic tomography with focus on their necessary modification when applied to 3D refractive index determination in micro-objects. Specifically the influence of diffraction phenomenon and radial run-out occurring during measurement are analyzed. The analysis are confirmed by results of measurements of 3D refractive index distribution in a multimode and single mode fibres.
