ABSTRACT:
A laser gyroscope for determining rotation of an area circumscribed by two closely adjacent optical fiber waveguides which serve as double laser cavities. Laser oscillation is restricted to one direction only in each optical fiber waveguide with the direction of oscillation in each waveguide being opposite to that in the adjacent optical fiber waveguide. Fractional parts of the laser radiation from the laser oscillation in each optical fiber waveguide are superimposed to develop a beat frequency therebetween which is proportional to the angular rotation of the area circumscribed by the two optical fiber waveguides.
