Reconstruction of longitudinal distributed incoherent sources Academic Article uri icon

abstract

  • same manner as appears in a coherently photographed hologram. The complex distribution of this degree of coherence is actually analogous to a Fourier hologram. Therefore, by illuminating a hologram with a transparency distribution of this degree of coherence in front of a spherical lens, we reconstructed the 3-D object in the vicinity of the lens's back focal plane. Inherently the 2-D hologram cannot contain all the 3-D information about the original object. Therefore this hologram cannot be transformed exactly back into the 3-D object, a problem that also exists in other conventional holograms. To overcome this holographic ambiguity problem we proposed recording a 3-D degree of coherence and having a precise representation of the 3-D intensity distribution emitted from the source. The precise reconstruction is achievable because this degree of coherence is proportional to the 3-D Fourier transform of the intensity distribution emitted from the 3-D source and observed form the
