Diffraction-Limited Imaging of Space Objects II.
Abstract
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).
