Abstract
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
