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： An accelerometer of the type in which a disk is mounted upon a vertical post. The accelerometer may be employed as a hydrophone, for example, including a watertight case, and forming a neutrally buoyant structure or may be suitable for hull-mounting. The disk comprises a planar honeycombed structure. A solid, dense ring-like peripheral mass is fixed to the central honeycombed structure to form a composite apparatus. The honeycombed central structure contributes enhanced stiffness without a corresponding increase in weight when compared with disks of solid fabrication while the peripheral concentration of mass increases radius of gyration sufficiently to offset gain dimunition due to increased stiffness so that an increase in figure of merit is obtained.

摘要： Interconnection mechanisms for a laser gyroscope assembly (10) enable it to be rapidly and non-harmfully assembled and disassembled prior to a more durable interconnection, to facilitate repair and rework. The assembly includes a fiber optic spool (12), an inner shield (16) and an outer shield (18), which are formed of a stress-annealed magnetic and generally malleable material. The outer shield comprises upper and lower portions or parts (30, 32) whose first and second end segments (62, 66) respectively terminate the portions. Segment (66) has angled intersecting conical surfaces (74, 76) which engage surfaces (65, 67) on segment (62). Stops (80, 83) are formed respectively on the ends of the segments so that a distal end (68) contacts an interior ledge surface (80) of outer shield (34), thereby to limit the mutual engagement and to center the segment configuration interfit. The position and location of the stop allows the intersecting edges of surface (65, 67) of outer shield (34) to precisely contact reverse taper segment (76) of surface (70) at a point beneath intersection (78) to ensure positive retention and mechanical locking of the upper and lower portions of outer shield (18). A plurality of notches (84) are positioned evenly about the periphery of the lower portion of the outer shield at its intersection of the upper portion. Tangs (90, 92) of a tool (88) are inserted in seriatim within the spaces for gradual disassembly of the upper and lower outer shield portions without harm thereto. Inner shield (16) includes a cover (28) having two pairs of projections (130, 132) which can snap together, and a top annular segment (126) which is engageable with a centering projection (138) on end (26) of the spool. When the cover is secured to the spool, the top annular segment is flexed, but not deformed, to provide a spring bias and positive retention and, consequently, a solid and chatter-resistant engagement in a robust mechanical connection even under severe dynamic environments.

摘要： A temporary latchable or clasping interengageable interconnection mechanism is provided for an optical gyroscope assembly (10) to enable it to be rapidly and non-harmfully assembled and disassembled prior to a more durable interconnection, to facilitate repair and rework. The assembly includes a fiber optic spool (12), an inner shield (16) and an outer shield (18), which are formed of a stress-annealed magnetically permeable, and generally malleable material. Should the assembly be dropped, bent or dented, their magnetic shielding properties will be compromised, which is the harm to be avoided by the temporary interconnection. Accordingly, the fiber optic spool (12) and the inner shield (16) are temporarily interconnectable with the outer shield (18) and its spacer ring (38) by interengageable elements having the ability to latch or clasp the shield and the spacer ring together to prevent or, at a minimum, resist disassembly therebetween. The temporary interconnection includes grooves (44, 46) respectively in a tubular wall (36) of the spool and in a corresponding element in the spacer ring. An O-ring (48) is positioned in the grooves, and provides easy assembly and disassembly. The O-ring also serves to center the inner shield within the outer shield to establish a concentric relationship between the two, to avoid a radial metal-to-metal contact therebetween, and to mitigate against chattering which otherwise would affect the fidelity of the gyroscope output.
摘要翻译：提供了一种用于光学陀螺仪组件（10）的临时可锁定或扣紧可相互接合的互连机构，以使其能够在更耐用的互连之前快速且无害地组装和拆卸，以便于维修和返工。该组件包括光纤线轴（12），内屏蔽（16）和外屏蔽（18），其由应力退火的可渗透的和通常可延展的材料形成。如果组件掉落，弯曲或凹陷，其磁屏蔽性能将受到影响，这是临时互连所避免的危害。因此，光纤卷轴（12）和内屏蔽件（16）可以通过可互锁的元件暂时与外屏蔽件（18）及其间隔环（38）互连，这些元件具有将屏蔽件和隔离环卡在一起的能力以防止或至少防止它们之间的拆卸。临时互连分别包括在线轴的管状壁（36）中的凹槽（44,46）和间隔环中的相应元件中。 O形圈（48）位于槽中，并且易于组装和拆卸。 O形环还用于使内屏蔽件在外屏蔽件内对中以在两者之间建立同心关系，以避免其间的径向金属对金属接触，并且减轻否则会影响陀螺仪的保真度的颤动输出。

摘要： A fiber optic displacement sensor includes a flexural disk assembly affixed to a mounting post that extends from a support base that is enclosed by a housing. Spiral wound optical fiber coils are mounted on opposite sides of the flexural disk with optical fiber leads extending from both the inner and outer diameters of the optical fiber coils and being optically coupled together to form an interferometer. An inertia ring connected to the periphery of the flexural disk has a plurality of peripheral slots therein for routing the optical fiber leads from the optical fiber coils to other components in the housing. The slots in the inertia ring are arranged to allow differing lengths of fiber to be wound circumferentially in different depth slots to accommodate mismatches in optical fiber lead lengths.

摘要： A fiber optic sensor comprises a flexural disk having a pair of fiber optic coils mounted on opposite sides thereof and connected together to form an interferometer that produces an output signal in response to acceleration of the flexural disk. The flexural disk is mounted in a housing having first and second end plates with a sidewall extending between them. The sidewall is formed to have an inwardly facing groove in which an outer edge portion of the flexural disk is mounted. A support member extends between oppositely facing portions of the first and second end plates and through a central passage in the flexural disk. A damping member is mounted on the central support member and arranged to exert a radial force on an inner edge of the central passage in flexural disk to dampen vibrations of the flexural disk and control the sensor output signal amplitude over a selected frequency band in order to maximize dynamic range.

摘要： A telemetry optical fiber has a first end optically coupled to a signal source/detection module. A conversion module is optically coupled to a second end of the telemetry optical fiber. The conversion module includes an interferometer having a pair of optical paths with an optical waveguide arranged to be included in each one of the optical paths. The interferometer is arranged to produce an interference pattern to indicate the phase relationship of optical signals input to the pair of optical paths from the signal source/detection module. A phase modulator is arranged to phase modulate optical signals guided by the optical waveguide. A sensor head that produces a voltage proportional to a quantity being measured is connected to the phase modulating apparatus and arranged to provide a modulating signal to the phase modulating apparatus such that the interference pattern indicates the magnitude of the measured quantity.
