摘要： An optical fiber interleaver and method for aligning the output channels to a set of nominal values in frequency space. The interleaver is formed of two optical fibers joined together at fused input and output couplers to define an input section, an interferometer section and an output section. Within the interferometer section, an element is arranged to vary the optical path length of at least one of the fibers in response to a feedback signal. The feedback signal is generated by examination of the intensity of a monitor signal at the output section that was applied at the input section.

摘要： A sensor coil for a fiber optic gyroscope. A continuous optical fiber is coated with bonding material of predetermined composition such as a thermoplastic material that exhibits a bond strength of at least 100 p.s.i. in tension, equivalent to at least 40 p.s.i. in shear. The coated fiber is arranged into a predetermined winding pattern whereby contacting portions of adjacent coil turns are bonded to one another. Void spaces between contacting portions of bonded turns reduce the volume of bonding material employed (as opposed to a filled potted sensor coil). The coil does not experience the differential in expansion along the axial and radial directions to the degree that has, for example, required the use of single flanged spools in the prior art. Its use with dual-flanged spools permits mounting arrangements that promote coil stiffness, thereby enhancing gyro performance in the presence of vibration.

摘要： A sensor coil for a fiber optic gyroscope is potted in polymer-based material selected for avoiding such temperature-related anomalies as bias spikes and bias crossings. The potting material is based upon a silicone composition characterized by a glass transition temperature that lies below and outside the operational range required for commercial or military operation. Predetermined fillers may be added to the silicone for bolstering stiffness (Young's modulus) within the polymer's rubbery region to reduce the gyro's bias sensitivity to vibration. Excellent bias thermal and vibration performance has been achieved with coils potted in silicone adhesive with a carbon-black filler.

摘要： An optical interleaver. The interleaver is based upon the Mach Zender interferometer. At least one of the optical paths joining opposed couplers of the arrangement includes an optical image transfer element intermediate the ends of fibers associated with the couplers. In one embodiment, the optical image transfer element is a single imaging lens whereas, in another embodiment, the element consists of an aligned pair of collimating lenses. During fabrication, optical positioning stages support the optical image transfer element and fiber ends to permit ready adjustment of &Dgr;&THgr;, the optical path length difference between the arms of the interleaver, to assure predetermined optical channel spacing of an input DWDM signal.

摘要： A fiber optic rotation sensor system having improved scale factor stability includes an optically pumped gain fiber arranged to provide optical signals to an integrated optics chip connected to a fiber optic sensing coil. An optical coupler receives optical signals from the gain fiber and provides the optical signals to an optical fiber. The optical fiber is arranged to guide optical signals from the optical coupler along an optical path toward the integrated optics chip such that optical signals from the gain fiber are input to the fiber optic sensing coil to form counter-propagating waves therein. The counter-propagating waves traverse the sensing coil and then combine in the integrated optics chip to form a gyro output signal. A depolarizer is placed in the optical path between the first optical coupler and the integrated optics chip to prevent random changes in the state of polarization of optical signals propagating between the gain fiber and the integrated optic chip.

摘要： A gyroscope assembly (10) includes a ring-shaped fiber optic coil (14) and a coil conforming enclosure (12, 16) of high magnetic permeability ferromagnetic material. The enclosure is ring-shaped to conform with the shape of the coil, and includes a portion (22) extending within the internal hole of the coil ring. Therefore, the coil is intimately and fully encased within high magnetic permeability material. In particular, the enclosure comprises a coil supporting spool (12) and a cover (16) secured to the spool. The spool includes a base (18) which is provided with a central hole (20) and a tubular wall (22) extending perpendicularly from the base. Coil (14) is bonded to base (18). Both the spool and the cover are formed of high magnetic permeability material, and the cover is placed about the fiber optic coil and attached to the spool. The coefficient of thermal expansion material used for the spool is matched to that of the coil pack to minimize stress imposed upon the fiber. An outer shield (28), roughly cylindrical in shape, may be further attached to the outside of the inner, toroidal shield, and the two shields are separated by a layer of low magnetic permeability material, such as of low magnetic permeability stainless steel or aluminum.

摘要： An interferometric rotation rate sensor is arranged to overcome effects of the unavoidable generation of intensity spikes in the modulated optical output. An electrooptical device is located within the optical path of the sensor for receiving the optical output signal from the sensor coil and transforming it prior to application to the photodetector. The electrooptical device is driven by a periodic electrical signal with a period equal to the loop transit time of light traveling through the sensor coil. By synchronizing the periods of attenuation with the predictable presence of spikes in the optical output, valid optical signal information is preserved while gyro electronics are sheltered from the results of optical intensity spiking.

摘要： A sensor coil for a fiber optic gyroscope. At least one dummy layer forms an integral structure with, and shares the thermal expansion characteristics of, a potted coil comprising a plurality of layers of windings of a first optical fiber. In a gyroscope, the potted coil is arranged to receive the output of a source of optical energy as a pair of beams that counter-propagate therein and to provide the resultant interference pattern, as gyro output, to a detector. The dummy layer displaces layers or windings of the potted coil from regions likely to contribute to Shupe bias effects.

摘要： A gyroscope component (10) and its variations (10a, 10b and 10c) includes a spool (12, 12a) which supports a ring-shaped fiber optic gyroscope coil (14). The spool has a base (26, 26a) which is provided with a central hole (38, 38a). A perpendicularly extending tubular wall (28, 28a) extends from the base or a cover (16, 16a), and may directly contact the coil or be separated therefrom by a non-adhesive material (29) or a space (30). The cover covers the spools and, with the spool and the tubular wall, forms a ring-shaped enclosure. Each coil has a generally trapezoidal shape and comprises an optical fiber winding wound about an axis and having a cross-sectional configuration that approximates a 45.degree. right triangle whose hypotenuse is formed by the sloped sides to provide a side which is sloped with respect to its axis. Three components (10, 10", 10"') are positioned respectively about three orthogonally disposed axes to form an assembly (50) and are supported within and enclosed by a housing (52). The arrangement of the enclosures positions the coils such that their sloped hypotenuse sides face one another. The spool (12, 12a), the cover (16, 16a), the tubular wall (28, 28a) and the housing (52) are formed of a ferromagnetic material having high relative (.mu./.mu.0) permeability.
