Abstract
It's significant and valuable to research the extremely weak signal detection technique, such as single photon detecting, for deep space objects (e.g. moon) and debris laser ranging. By single telescope transmitting the laser and multiple telescope receiving echo laser photons, it is feasible to increase the successful detecting probability. Here the optical path and the laser ranging computer system are researched, and are applied into satellites laser ranging experiments. The results indicate this system is effective and capable of the middle earth orbit even geosynchronous earth orbit satellites laser ranging. Next step, it will be used to measure the debris objects.
