Transmission phase images with nanometric axial accuracy are numerically reconstructed from holograms acquired for different orientations of the rotating sample; then the threedimensional refractive index spatial distribution is computed by inverse radon transform. A precision of 0.01 for the refractive index estimation and a spatial resolution in the micrometer range are demonstrated.[MVD]Holography : HolographyHolography : Computer holographyImaging systems : Three-dimensional image acquisitionImaging systems : Tomographytext::journal::journal article::research article
