摘要： An integrated module for a fiber optic gyroscope system includes a fiber optic sensing coil arranged to sense rotations about a sensing axis via the Sagnac effect comprises a substrate, an optical waveguide formed on the substrate, a light source comprising a doped waveguide formed on the substrate. The light source and the optical waveguide are arranged to produce counterpropagating light waves in the fiber optic sensing coil. The light source may be formed as a rare earth doped polymer waveguide or as a rare earth doped glass waveguide.

摘要： Techniques for adding and dropping a wavelength or band using two individual optical paths are disclosed. The two individual optical paths are configured to maintain one path active while the other is in stand-by setup or tuning mode. While one optical path is adding and dropping a wavelength, the other optical path can be calibrated for a new wavelength. When an optical switch switches from one path to another, a new wavelength to be added and dropped is effectuated.

摘要： A plurality of air-backed elongate mandrels are arranged in an planar array such that their longitudinal axes are parallel. A length of a first optical fiber is wound around portions of each mandrel in a first group of the mandrels for exposure to the parameter. The first optical fiber is arranged such that exposing it to the parameter to be sensed causes the length of the first optical fiber to increase and decrease in direct proportion as the parameter increases and decreases. A length of the second optical fiber is wound around a second group of the mandrels for exposure to the parameter. The second optical fiber preferably is arranged such that exposing it to the parameter to be sensed causes the length of the second optical fiber to increase and decrease in inverse proportion as the parameter increases and decreases.

摘要： An acceleration insensitive interferometric hydrophone sensor having increased sensitivity comprises a rigid cylindrical support mandrel that is coaxial with and between thin walled sense and reference mandrels. Flanges on the reference and support mandrels form air filled cavities above and below optical reference and sense fiber windings, respectively, that are symmetrically wound on associated mandrels. The walls of the sense and reference mandrels are thin so that they both respond to the same incident acoustic wave signal although 180.degree. out-of-phase. A central collar on the support mandrel provides an acceleration insensitive location for making attachment to the hydrophone. In another embodiment, the reference mandrel is much thicker than the sense mandrel and cavities supporting the sense fiber are caused to operate as acoustic impedance mismatches for rendering the reference fiber winding substantially insensitive to and acoustically decoupling it from an incident acoustic pressure wave signal. In yet another embodiment which does not employ a reference mandrel, the reference fiber is wound around the support mandrel in cavities above the latter that are caused to operate as acoustic mismatches. The junctions of the mandrels are preferably sealed for isolating the wound length of reference fiber and cavities from fluid in which the hydrophone sensor is located.

摘要： A hydrophone includes a plurality of hydrophone components separated by finite spacings and interconnected to provide a single output signal. Each hydrophone component is based upon a single-mandrel design in which a cylindrical body is apportioned into sensing and reference sections. The sensing sections comprise coaxial arrangements of pliant inner and outer cylinders separated by an annular airspace while the adjacent reference sections comprise solid-walled cylinders. Finite separation distances between the hydrophone components result in reduced flow noise occasioned by increased sensing area while detection sensitivity is maintained.

摘要： The inner surface affixation system and process is a method for affixing wound optical fibers on the inner surface of a hollow cylinder. It is useful, for example, in the manufacture of rigid mandrel-based fiber optic sensors. The optical fibers of a sensor wound on the inner surface are less susceptible to damage than are optical fibers wound on the outside of the mandrel.The process requires that the fibers be supported on a cylinder, which is coated with an adhesive and placed within the sensor mandrel cylinder, at which time the circumference of the supporting cylinder is expanded, causing the fibers to engage the inner surface of the sensor mandrel cylinder. The adhesive is then cured, holding the fibers in place on the inner surface of the sensor mandrel cylinder while the supporting cylinder is contracted and removed from the sensor mandrel cylinder.
