ABSTRACT:
An improved compact optical gyro is provided wherein a beam of light is split and introduced into both ends of an optic coil whose rotation is to be sensed. At least one frequency shifter is placed to affect the frequency of the beam to introduce or adjust a nonreciprocal phase shift. The beams are then mixed back together and the resultant beam is detected and analyzed by suitable circuitry to provide an output indicative of the rotation of the light path.
