Abstract
In the existing techniques of measuring rotation angel sin high-sped, the resolutions of measuring rotation angles and the rotation velocities are restrictive for each other. In this paper, a neoteric measuring method is proposed, to which the double-frequency heterodyne interference technique and spiral metal reflector were applied, and it could improve the restrict of the rotation velocities.
