Image Reconstruction from Interferometer Data
1993
Abstract : In blind tests, we successfully reconstructed images from data simulated to have some of the defects that data coming from the multi-aperture amplitude interferometer (MAAI) at the University of Maryland would have. We also successfully reconstructed good-quality images from phaseless data collected by ERIM's experimental range-angle interferometric imaging system. These successes in reconstructing images with phaseless interferometer data demonstrate the possibility of obtaining fine-resolution images with large, low- cost, light-weight, aberrated optical systems, despite the kinds of noise and other errors that are present in real data. We also showed that it is feasible to insert a beam deviator in the MAAI that would allow us to measure the lower spatial frequencies that are crucial for reconstructing images from low-light- level data....
