Optical Detection of Space Debris Using a Large Achromatic Coronagraph

摘要

The threat of space debris seems to increase steadily; accordingly, new methods of detection are need. We present a theoretical approach of this problem, assuming the use of a new generation large achromatic ground based coronagraph. Few interesting results are presented including the estimation of the probability of being able to systematically observe small size space debris in a large range of altitudes.
