Abstract: A fiber optic displacement sensor (10) includes a flexural disk (16) assembl y affixed to mounting post (20) that extends from a support base (22). The flexural disk (16) assembly is mounted in a housing (101). Spiral wound optical fiber coils (12, 16) are mounted on opposite sides (16A, 16B) of the flexural disk (16) with optical fiber leads (12A, 12B, 14A, 14B) extending from both the inner and outer diameters of the optical fiber coils (12, 14). Optical signals output from the coils (12, 14) are coupled together to form an interferometer (70, 114). An inertia ring (60) connected to the periphery of the flexural disk (16) has a plurality of peripheral slots (68, 92, 38) therein for routing the optical fiber leads (12A, 12B, 14A, 14B) from the first and second optical fiber coils to other components in the housing (101 ). The inertia ring (60) has curved side edges (61, 63) formed such that the optical fiber leads (12A, 12B, 14A, 14B) may be spiral wound thereon between the first and second coils (12, 14) and the peripheral slots (68, 92, 98) to prevent damage to the optical fiber leads (12A, 12B, 14A, 14B) from sharp bends. The slots (68, 92, 98) in the inertia ring (60) are arranged to allow differing lengths of fiber to be wound circumferentially in different depth slots to accommodate mismatches in optical fiber lead lengths (12A, 12B, 14A , 14B), which allows the fiber leads (12A, 12B, 14A, 14B) to ultimately exit t he flexural disk (16) together and take the same path to the coupler (76) to provide improved common mode rejection of extraneous environmentally-induced phase shifts.

Abstract: A sensor array cable and method of construction thereof utilizing a sensor/interlink assembly to facilitate the relatively easy and inexpensive installation of a sensor device in a cable that includes a strength member to provide tensile strength to the cable, optical fibers or wires for carrying electrical or optical energy to and from the sensor device, and a protective outer jacket. A portion of the protective outer jacket is removed allowing access to the inner strength member and optical fibers. A segment of the strength member is removed and an interlink/sensor assembly is installed in its place. The interlink serves to maintain the tensile strength of the cable. Optical fibers and/or electrical wires are connected to the sensor device for operation. The interlink/sensor assembly and associated optical fibers and electrical wires are then enclosed in an overmold which is sealed to the outer protective jacket.

Abstract: The design and method of fabrication for an acoustic sensor module (10) for mounting on the hull of a submarine or surface ship is disclosed. The design involves the use of molded alignment structures (140) to position the acoustic sensors (20) within a two part shell (40) prior to the two part shell (40) being filled with an acoustic medium (30) used to encapsulate the acoustic sensors (20). The disclosed design and fabrication method reduce tooling requirements and eliminate a significant amount of assembly labor in fabricating hull mounted sonar arrays.
