Paper Abstract

The scanner of orthogonally tilting double prisms is researched for testing the performance of tracking performance in inter-satellite laser communications for the first time. With the reduction ratio of more than a hundred times from the change rate of deviation angle of beam to that of tilting angle of each prism, the scanner can reach the scanning accuracy of sub-microradian order but facilitates the mechanical structure design. The theoretical analysis performed, as well as the validation experiment, indicates the scanner can meet the requirements of the scanning accuracy superior to 0.5 μrad with the scanning range greater than 500 μrad.
