A connector anchors as outer conductor onto a cable and connects the outer conductor to the cable's inner conductor without exposing the inner conductor to the ambient environment. The connector includes a longitudinally split cylinder having a thicker center wall and a pair of flanking walls that wrap around a notched section of the cable and contact the inner conductor. An inner ring with multiple recessed interior circumferential grooves wraps around and overlaps the split cylinder so that the grooves will emboss and grip the cable's jacket without piercing the jacket when swaged. The outer conductor is placed over the inner ring. An outer ring anchors the outer conductor to the inner ring when swaged.

Corrosion resistant, environmentally sealing, electrically conducting, cable connector

A corrosion resistant, environmentally sealing, swaged-on conductive fitting for a coaxial cable is provided. The cable has inner and external conductors. A stepped intermediate ring is fitted over exposed lengths of trimmed layers of the inner conductor and abuts a trimmed end of a jacket that covers the inner conductor. An inner ring having a socket with interior recessed circumferential grooves is placed over and swaged against the intermediate ring so that the grooves overlap the cable's jacket and are embossed into and anchor the inner ring to the jacket. The external conductor is anchored between the inner ring and an outer ring when the outer ring is swaged. An electrically conductive path is provided from said external conductor through the inner and intermediate rings to the inner conductor without exposing the inner conductor to a corrosive environment.

Electrically conducting, environmentally sealing, load transferring cable termination fitting

An improved corrosion-resistant magnetic influence minesweeping cable is provided. The cable produces a magnetic field that simulates a ship's magnetic signature as the ship passes through the sea. It has an outer anode conductor made of titanium-clad copper with mixed metal oxide at its aft end, an outer cathode conductor made of nickel-clad copper at its forward end, an inner conductor made of aluminum that runs the length of the cable, and a steel core strength member that also runs the length of the cable. The outer anode conductor is in electrical contact with the inner conductor. The outer cathode conductor is insulated from the inner conductor. The outer cathode conductor and the inner conductor can be connected to an electrical power source onboard a towing vessel.

A system and method of reconstructing a three-dimensional image of an object is provided. The system includes a single camera including a pinhole lens and having a surface defining an image plane. The single camera can be arranged to move along a linear path relative to the object and is configured to capture images at predetermined locations along the linear path such that at least a portion of the captured adjacent images overlap. The system includes a processor that can be programmed with an image processing logic that enables the processor to create a three-dimensional image of the object.

Optical 3-d surface tomography using depth from focus of partially overlapping 2-d images

A method is provided for the generation an image in a turbid medium. After illuminating locations along a each of three adjacent lines using beam(s) of light, a camera is activated to generate three separate images. The second line is between the first and third lines. In terms of amplitude associated therewith, a portion of each of the first image and third image are subtracted from the entirety of the second image to generate a resulting image.

Method of generating an image in a turbid medium

A system for forming an image of an object in a turbid medium comprises a light source for producing a coherent light beam of a selected frequency that is divided by a beamsplitter into a reference beam directed along a first optical path and a signal beam directed along a second optical path where the object to be imaged is located. The signal beam impinges upon the object and reflects back toward the beamsplitter. The reference beam is modulated to shift its frequency. A mirror reflects the reference beam back toward the beamsplitter for combination with the signal beam to produce an output optical signal. A photodetector receives the output optical signal from the beamsplitter and produces an electrical signal having a frequency related to shifts in frequency between the reference beam and the signal beam and having an amplitude proportional to the image intensity. A heterodyne detector connected to the photodetector produces a beat signal when the first and second optical paths have matching lengths so that the location of the point on the object where the signal beam reflected can be determined. By scanning the signal beam across the object, the system determines locations of a number of points on the object sufficient to form its image.

Coherent imaging in turbid media

A method and system for target detection processing transmits energetic pes into a media in which the energetic pulses propagate diffusively. Diffusively propagating reflections of the energetic pulses from a target are transformed into corresponding wave propagating reflections satisfying a conventional wave equation. The wave propagating reflections are then processed in accordance with a synthetic aperture processing technique.

Synthetic aperture processing for diffusion-equation-based target

A DC superconductor quantum interference device (i.e. DC SQUID) is used in a flux-locked loop as a sensitive detector of magnetic flux. Prior art devices of this sort had a transfer function which was frequency-limited by the transfer function of impedance matching circuitry which is used to connect the DC SQUID with the first preamplifier, which amplifies the DC SQUID signal before it is applied to a detector circuit. The present invention corrects this frequency limitation by creating a compensating circuit having a transfer function which is the inverse of that of the impedance matching circuitry, and inserting it in the system after the first preamplifier and before the detector circuit.
