Phase information plays an important role in three-dimensional (3D) imaging. Digital holography (DH) has been widely used in 3D imaging to reconstruct the phase distribution from optical fields. The transport of intensity equation (TIE) is a way to retrieve true or unwrapped phase from phase objects with multiple captures of intensity images along the light propagation direction. In this thesis, solving TIE with the help of the transport of phase equation (TPE) is first proposed. Combining TIE with TPE can further improve the accuracy of the Fourier transform based TIE solution with no extra captures of intensity images and little sacrifice of computational efforts. Next, the combination of DH and TIE is investigated to retrieve phase without any phase unwrapping and multiple captures of intensities. Finally, correlation of holograms is proposed to extract 3D surface features directly from 2D holograms. As an illustration, an application to face recognition is presented.
