Microinterferometric tomography for reconstruction of 3D refractive index distribution in plane microelements

The paper gives a review of interferometric 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 is confirmed by results of measurements of 3D refractive index distribution in a multimode and single mode fibers. Additionally the discussion of future work at photoelastic tomography applied for microobjects is given.
