Abstract
A hard x-ray/medium energy gamma-ray telescope is being developed using coded aperture imaging. The image recorded on the detector has to be cross correlated to deconvolve the sky map. We have developed a deconvolution method using the 2-D discrete Fourier transform, whose goal is to improve the separating power of these reconstructed maps. The results and limits of the method are discussed.Keywords
