description	The invention discloses an optical fiber gyroscope for three-self inertial navigation, which adopts a sensor and drive detection separation mode and comprises an optical angular velocity sensing unit and a photoelectric drive detection module, and the optical angular velocity sensing unit comprises an optical fiber ring and an integrated optical phase modulator. The photoelectric driving detection module comprises an erbium-doped light source, an optical fiber coupler, a photoelectric detector, a light source driving circuit, a signal detection circuit, a control circuit and a detection module structure. The erbium-doped light source has the characteristics of high power and high wavelength stability, the signal-to-noise ratio and linearity of the system are improved, the erbium-doped light source is suitable for sensitive high-resolution rotating speed, and meanwhile, the physical separation of the optical angular velocity sensing unit and the driving detection module can reduce starting drift. 本发明公开了一种三自惯导用
