In this paper we show how the techniques of image deconvolution can increase the ability of image sensors as, for example, CCD imagers, to detect faint stars or faint orbital objects (small satellites and space debris). In the case of faint stars, we show that this benefit is equivalent to double the quantum efficiency of the used image sensor or to increase the effective telescope aperture by more than 30% without decreasing the astrometric precision or introducing artificial bias. In the case of orbital objects, the deconvolution technique can double the signal-to-noise ratio of the image, which helps to discover and control dangerous objects as space debris or lost satellites. The benefits obtained using CCD detectors can be extrapolated to any kind of image sensors.
在本文中，我们展示了图像反卷积技术如何提高图像传感器（例如 CCD 成像仪）检测微弱恒星或微弱轨道目标（小卫星和空间碎片）的能力。在微弱恒星的情况下，我们证明这种优势相当于将所用图像传感器的量子效率提高一倍，或者在不降低天体测量精度或引入人为偏差的情况下，将有效望远镜孔径增加 30%以上。在轨道目标的情况下，反卷积技术可以将图像的信噪比提高一倍，这有助于发现和控制空间碎片或丢失的卫星等危险物体。使用 CCD 探测器获得的好处可以外推到任何类型的图像传感器。
