Abstract: In this talk both interferometric and non-interferometric methods for 3D imaging will be discussed, with particular emphasis on multi-wavelength digital holography and transport of intensity.  Mutli-wavelength digital holography is applied to reconstructions of various objects.  Besides demonstration of very large and very small synthetic wavelengths, of particular recent interest is the 3D reconstruction of level 3 details in latent fingerprints.  Also, it is demonstrated how the transport of intensity equation, along with its coupled transport of phase equation can be used to obtain better estimates of imaged  phase and 3D profiles.  The interrogated phase is from self-phase modulation of a laser beam in a thermal medium.
