摘要： An interferometric fiber optic gyroscope having a wavelength-sensitive splitter which has a splitting ratio that changes according to light wavelength. A feedback circuit indicates any difference that there might be in the intensities of counterpropagating beams in the sensing loop of the gyroscope, and provides a signal to the light source to change the light wavelength in a direction to cause the splitter ratio to change so as to equalize the beams' intensities for eliminating the Kerr effect.

摘要： An error compensator for a resonator fiber optic gyroscope extracting characteristics from the output signal of a photodetector, receiving electromagnetic waves from the resonator, and combining them to result in a determination of substantially the rotation rate error that is due to the effect of a nonlinear refractive index occurring in the resonator. This determination can be used to compensate the system output signal to eliminate rotation rate errors of such a nature therefrom.

摘要： A passive ring resonator gyro is constructed of an electromagnetic waveguide ring path which causes a specified rotation of the polarization of the waves, once for each round trip through the ring path. For an optical fiber ring path, a splice at some point is introduced in the ring path in which the fiber ends are rotated relative to each other in order to effect polarization rotation.

摘要： In many optics applications, it is desirable to retard the polarization of a light wave, i.e., to change the polarization state of a light wave. In a method for retarding polarization of a light wave, a first linear polarization-maintaining fiber having a first beat length is spliced to a second polarization-maintaining fiber having a high birefringence and a second beat length. The second fiber is then cleaved to a length which is a fraction of the second beat length. The first fiber and the second fiber may be secured in a removable or permanent capillary. A light wave is transmitted into the first fiber and the polarization state of the light wave is determined. To adjust the polarization state, the second fiber may be lapped against an abrasive substance. The second fiber may be repeatedly lapped until a desired polarization state is achieved. In an alternate method, a first linear polarization-maintaining fiber is spliced to a second polarization-maintaining fiber having a high birefringence and a beat length. The second fiber is cleaved to a length which is a fraction of the beat length and a third fiber is spliced to the second fiber. A light wave is transmitted through the fibers and the polarization state of the light wave is determined. All or part of the second fiber may be heated to adjust the polarization state of a light wave. The second fiber may be repeatedly heated until a desired polarization state is achieved.
