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.
