Abstract:

As an alternative to holographic laser radar, AMPS will develop a 3-D imaging concept that collects far-field intensity speckle patterns. This kind of measurement greatly relaxes the tolerances on vibration and coherence length. However, phase retrieval will be required to retrieve a 3-D image. Phase retrieval algorithms typically utilize some type of prior knowledge about the object. In industrial metrology and missile-imaging problems the objects will be opaque to the illumination and will appear as a warped 2-D surface embedded in a 3-D space. The opacity constraint promises to be very powerful since it greatly reduces the class of feasible objects from which to choose an estimate. We propose to demonstrate, in computer simulation and with laboratory data, 3-D imaging of opaque objects by using phase retrieval.
