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. This map suffers from blurring due to the spatial resolution of the position sensitive detector and to the simple point spread function of the cross-correlation method. We have developed and tested an iterative method which improves the separating power of the reconstructed maps. The results and limits of the method are discussed.
正在利用编码孔径成像技术研制一种硬X射线/中能伽马射线望远镜。探测器上记录的图像必须进行互相关处理以解卷积出天图。由于位置灵敏探测器的空间分辨率以及互相关方法简单的点扩散函数，该天图存在模糊现象。我们已经开发并测试了一种迭代方法，该方法提高了重建天图的分辨能力。文中讨论了该方法的结果和局限性。
