Scientific paper
This report describes the results of the second year of a three-year research program to investigate methods for obtaining diffraction-limited images of space objects, despite the turbulent atmosphere, by reconstructing images from data provided by optical interferometers (particularly stellar speckle interferometry). Accomplishments include the following: (1) Improved image reconstruction algorithms were developed. (2) A better understanding of modes of stagnation of algorithms was developed. (3) The performance of the shift-and-add image formation method and of one recursive algorithm were investigated. (4) A second recursive algorithm was shown to suffer from a uniqueness problem. (5) A potential new remote sensing application of the iterative reconstruction algorithm was explored. (Author).
