Two-mirror Resonators as Rotation Sensors |
|
| Abstract: | A method for using a two-mirror resonator as a rotation sensor is described. The system is more sensitive than a ring gyro or a Sagnac interferometer enclosing the same effective area. This additional sensitivity over the Sagnac limit is shown to arise only in non-planar closed path systems in which the counter-propagating beams follow slightly different paths. The shear between the two beams is solely due to the rotation. |
