摘要：本发明公开了一种自注入锁定光纤激光陀螺，它由光纤激光器及探测器、差频信号处理电路组成，光纤激光器由带尾纤的半导体激光器、单频分布反馈光纤激光器DFB、光纤环、光纤耦合器组成，而光纤环则由波分复用器、隔离器、增益光纤及光纤耦合器组成。两个带增益光纤的光纤环形成了两个各自独立的谐振腔，DFB分别向其中注入种子激光、将其工作波长锁定，隔离器则使激光工作在单向行波状态，且一个环中的激光传输方向为顺时针方向；另一个环中的激光传输方向为逆时针方向。本发明消除了均匀展宽增益介质中的空间烧孔现象以及因后向散射而造成的闭锁效应，并使两个环形腔中的激光工作在线宽很窄的稳定单纵模状态。可采用差频信号进行检测。

摘要： An improved optical fiber gyroscope is provided to determine the angular velocity of an optical system. A beam of light emitted from a coherent light source are split into first and second light components. The first light component is further split into third and fourth light components while the second light component is further split into fifth and sixth components. The third and fifth light components are passed through a coil-like optical fiber in opposite directions to each other while the fourth and sixth light components are passed through an optical modulator in opposite directions to each other. The third and fourth light components are made to be interfered in a photodetector while the fifth and sixth light components are made to be interfered in another photodetector. From the outputs of the photodetectors, the above angular velocity is determined.

摘要： Waveguide includes fork with first and second bifurcated ends coupled to loop section and separated by angle determined based on velocities of portions of quantum mechanical wavefunction of atoms traveling above waveguide. Waveguide propagates blue-detuned laser having first evanescent field that repels atoms away from waveguide and red-detuned laser having second evanescent field that attracts atoms toward waveguide, together creating potential minimum/well. Laser cooling atoms, causing atoms positioned in potential minimum/well to move toward first fork section following potential minimum/well. Atomic state initialization section initializes atomic states of atoms to known ground-state configuration. Beam splitter section splits quantum mechanical waveform of each atom above surface of diverging waveguide into first portion at first velocity that travels into first end of first fork section into first loop section and second portion at second velocity that travels into second end of first fork section into first loop section.

摘要： A resonator fiber optic gyroscope (RFOG) is provided. The RFOG includes a fiber coil, first and second lasers, first and second phase modulators, and a common phase modulator. The first laser generates CW input light for propagation in the CW direction of the fiber coil. The second laser generates CCW input light for propagation in the CCW direction of the fiber coil. The first phase modulator modulates the CW input light with modulation frequency f1=(n+0.5)*FSR. The second phase modulator modulates the CCW input light with modulation frequency f2=(m+0.5)*FSR so that overlap of major sidebands is avoided. The phase modulation amplitudes of the first and second modulators substantially suppress the optical carrier components of the CW and CCW input light. The common phase modulator is configured to modulate the CW and CCW input light with a common phase modulation frequency and a common phase amplitude.
