Abstract

Fourier telescopes are an effective approach for providing images of hard x-ray and gamma-ray sources found in the sky. Sufficient coverage of the (u,v) plane is a requirement for effective imaging. Unfortunately, this requirement is diametrically opposed to the requirements to minimize instrument weight and cost which translate into minimizing the number of grids. This paper reports on a telescope design incorporating only one real and imaginary set of grid pairs which provides superior imaging performance at a significantly reduced cost.
