Abstract
A device is provided for rotation rate measurement. The device includes a laser, pre- and post-selection polarizers, a birefringent crystal, and a detector. The laser emits a photon beam. The crystal separates the beam into separate parallel beams by phase difference in response to the rotation rate as measured by the detector.
Claims4
A device for measurement of rotation rate, said device comprising:
- a laser for emitting an optical beam of photons;
- first and second polarizers for preselection and post-selection;
- a birefringent crystal for splitting said optical beam of photons into a pair of parallel beams of photons, said optical beam having an incidence angle;
- a detector for registering said parallel beams of photons;
- and
- a platform onto which said laser, said polarizers, said crystal, and said detector are sequentially disposed, wherein
- said parallel beams are distinguished by horizontal and vertical polarizations relative to said birefringent crystal, and separate by phase difference in response to the rotation rate.
