Paper Abstract

The original scanner of tilting orthogonal double prisms is studied for testing the tracking performance in inter-satellite laser communications. Two prisms respectively rotate around the horizontal axle and the vertical one within the admissible range to determine the corresponding orientation and position of the passing beam, therefore the high accuracy deviation angle of passing beam can be performed. The test experiments performed with autocollimator and interferometer, as well as the theoretical analysis, indicates that the scanner can meet the requirements of the deviation accuracy superior to 0.5 μrad with the deviation range greater than 500 μrad, which accords to our design requirements.
