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. Multi-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. Other applications of multi-wavelength digital holography resulting from realization of very small and very large synthetic wavelengths are discussed. Applications of digital holographic tomography to 3D virtual reality is demonstrated. Also, it is shown 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. Other methods of solving the transport of intensity equation are also discussed and compared.
