Paper Abstract

Two techniques we have used for determining mirror positions in multiple-aperture telescope arrays are described. Our design criteria is the maximization of the contiguous central core diameter of the optical transfer function for the telescope system. The first technique is applicable to arrays with a relatively small, O(10), number of apertures and is essentially an exhaustive search with a simple in-line test which allows the search space to be 'pruned' by an order of magnitude. In the second technique, arrays of a large number of apertures are designed using a fractal approach by recursively combining the results from several array patterns with fewer apertures. Both techniques are demonstrated for one and two dimensional designs and can be extended for higher dimensions if needed.
