摘要： A fiber optic sensing system for determining the position of an object requires a light source, an optical fiber, a fiber optic splitter, a fiber tip lens, an optical detector and signal processing circuitry. Light emitted by the light source is conveyed via optical fiber and the splitter to the lens and onto an object, such that at least a portion of the light is reflected by the object and conveyed via fiber and the splitter to the detector. Signal processing circuitry coupled to the detector determines the position of the object with respect to the lens based on a characteristic of the reflected light. The system is suitably employed with a hydraulic accumulator having a piston, the position of which varies with the volume of fluid in the accumulator, with the system arranged to determine the position of the piston, from which the volume can be calculated.

摘要： A microelectromechanical shutter system includes an actuator beam formed in a substrate, at least one actuator electrode spaced apart and electrically isolated from the actuator beam, the at least one actuator electrode angling away from a base of the actuator beam to actuate the actuator beam using a zipper action, and a fiber-optic channel in the substrate to receive a fiber-optic cable. A shutter mirror is included on a distal end of the actuator beam, with the shutter mirror in substantial alignment with a centerline of the fiber-optic channel. Upon application of a voltage between the actuator beam and the at least one actuator electrode, an electrostatic force is created between them to move the shutter mirror across the end of the fiber-optic channel.

摘要： A fiber optic hydrophone is formed as a single interferometer having widely separated interferometer segments formed in each of a pair of optical fibers. The interferometer segments are designed to allow averaging of the effects of local noise sources over a broad area in order to increase the acoustic signal-to-noise ratio. The interferometer segments also allow deployment of the hydrophone around sharp bends. A first optical fiber is formed into a plurality of spatially separated outer coils. A second optical fiber is formed into a plurality of inner coils corresponding to the outer coils. The inner and outer coils are preferably arranged in concentric pairs to form a plurality of sensor segments. A plurality of spacers is arranged such that a spacer is between successive sensor segments. The spacers are formed to guide the outer and inner optical fibers between successive sensor segments such that changes in the physical parameter between the sensor segments produce no phase difference between optical signals guided by the outer and inner fibers. The outer and inner coils are preferably arranged for exposure to the parameter such that changes in the parameter at each sensor segment produce opposite phase changes between the optical signals in the outer coils and the corresponding outer coil.
