title: Research on a scanner for tilting orthogonal double prisms.
abstract: The original scanner for tilting orthogonal double prisms is studied to test the tracking performance in intersatellite laser communications. With a reduction ratio of more than 100 times from the change rate of the angle of beam deviation to that of the tilting angle of each prism, the theoretical analysis performed, as well as the verification experiment, indicates that the scanner can meet the requirements of the scanning accuracy superior to 0.5 microrad with the scanning range greater than 500 microrad and can facilitate the mechanical structure design.
