  • Differential interferometer with improved cyclic nonlinearity
    Patent number: 7196797
    Abstract: An interferometer system includes a plane mirror interferometer, a turning mirror, a retardation plate assembly having a retardation plate that can be adjusted and then fixed, and a retroreflector. A light beam travels in a path comprising the plane mirror interferometer, the turning mirror, the retardation plate assembly, and the retroreflector. The retardation plate assembly may include a plurality of bearings, a ring riding on the bearings, the retardation plate mounted to the ring, and a plunger pushing the ring against the bearings. The retardation plate may be fixed by adhesive after determining an orientation that produces little polarization leakage in the system.
