Abstract
Design of a fiber optic gyroscope FOG using a photosensitive line to scan interferograms is proposed. Shift periods depends mainly on the change of the phase of counter light waves propagating along the closed loop in opposite directions while rotating loop around an axis that is normal to its plane. Phase shift is proportional to the angular velocity Ω and the area of the circuit S which is bypassed by the counter-propagating waves. Proposed FOG design significantly reduces the impact of the following optical noise factors: zero drift, Rayleigh scattering, the Kerr effect, etc.
