Publication number: 20050206904Abstract: Novel spectroscopy techniques using entangled photons are disclosed. In one technique, entangled photons are directed to a sample of interest, while the photons with which they are entangled are resolved according to frequency. The photons transmitted by or reflected from the sample and the frequency-resolved photons are detected. Such detection may be by way of an electronic coincidence counter or a biphoton sensitive material, which absorbs entangled photons while allowing other photon pairs to pass. Detection information is used to derive spectroscopic properties of the sample. In another technique, a Fourier transform spectroscopy technique using entangled photons is disclosed. Entangled photons are directed to a sample, while the photons with which they are entangled are directed to a Michelson interferometer. The photons transmitted by or reflected from the sample and the photons leaving the Michelson interferometer are detected.Type: ApplicationFiled: July 28, 2004Publication date: September 22, 2005Applicant: General Dynamics Advanced Information Systems, IncInventor: Thomas Zaugg

Publication number: 20050184899Abstract: A method according to a first aspect may include performing a first analog-to-digital (A/D) conversion using an A/D converter. Data associated with this first A/D conversion may be read using a processor. A command may then be issued from a processor when the reading of the data has started. This command may instruct the A/D converter to perform a second A/D conversion. This data may then be stored in a data structure located within a memory device while the A/D converter is performing the second A/D conversion. In addition to performing such pipelined A/D conversions, the present invention may include a system, method and software for filtering out noise in a voltage measurement after the voltage measurement has been converted to a digital signal by omitting the highest and lowest voltage values and averaging the remainder of the voltage values, thereby reducing noise in the voltage measurements.Type: ApplicationFiled: November 12, 2004Publication date: August 25, 2005Applicant: General Dynamics Advanced Information Systems, Inc.Inventors: Kurt Witte, Andrea Wright

Patent number: 6931182Abstract: A bypass cable assembly that protects bypass fibers from one end of a hydrophone assembly to the other, avoiding subjecting the fiber to excessive tow-induced drag loading or the loading incurred during handling of the module. The bypass cable assembly comprises an elastic woven fiber cable with a jacketed optical fiber attached to one side of the cable in a sinusoidal pattern. The cable is attached to a woven fiber protection assembly proximate at each end of the hydrophone assembly. Along a central portion of the cable, the cable transitions to be substantially parallel to the module central axis and is disposed alongside the hydrophone assembly. Elongation of the cable causes the period of the sinusoidal pattern to increase without imparting damaging stress to the optical fiber. The elastic woven fiber cable is periodically attached along the central portion of the cable to positioning tape of an internal strength member.Type: GrantFiled: October 16, 2003Date of Patent: August 16, 2005Assignee: General Dynamics Advanced Information Systems, Inc.Inventors: Donald A.

Patent number: 6873285Abstract: An along-track alignment and formatting system (ATAFS) formats synthetic aperture radar (SAR) data to align and format signals from scatterers in a scene to achieve an ideal data format in the along-track dimension in which such ideal data format leads to improved image quality of an image based on the SAR data and/or reduced computational burden for generating an image based on the SAR data. Two aspects of the ATAFS include: 1) the division of data stabilization into two distinct steps; and 2) the along-track (or slow-time) migration of signal support of scatterers as a function of their along-track location. A suite of SAR image formation algorithms use the ATAFS in conjunction with conventional signal processing stages to transform input coherent signal data into a complex image with image quality and geometric accuracy commensurate with the inherent information content of the input data.Type: GrantFiled: July 9, 2003Date of Patent: March 29, 2005Assignee: General Dynamics Advanced Information Systems, Inc.Inventors: Walter G.

Patent number: 6870997Abstract: A fiber splice tray for connecting optical fibers between hydrophone modules, allowing each module to be independently assembled. The tray houses the optical fiber in a small space envelope, and allows positioning of a spliced fiber along a straight portion of an internal groove. The internal groove has alternate paths for housing the fiber. The internal groove comprises two opposing parallel sections and two arcs at both ends of the parallel sections, making two continuous looped alternative fiber paths. The internal groove may further comprise two sections that are alternatives to the parallel sections and that cross each other in the middle of the tray. The various alternative fiber paths make it possible to position a splinted optical fiber splice or splice sleeve, which cannot tolerate a bend in the path, in a straight section of the groove.Type: GrantFiled: June 28, 2003Date of Patent: March 22, 2005Assignee: General Dynamics Advanced Information Systems, Inc.Inventors: Donald A.
