Intensity Interferometry has been previously used to measure angular diameters 
of stars. Information recieved from Intensity Interferometry is proportional 
to the squared magnitude of the fourier transform of the image in the sky. 
Eventhough the phase is lost in the measurement process, recent work suggests 
that the phase can indeed be recovered by using the Cauchy-Riemann equations, 
and so full image reconstruction is possible. Image recovery of realistic 
astrophysical scenarios is implemented in one and two dimensions, and the 
capabilities and limitations of image reconstruction with ground based 
telescope arrays are discussed.
