Title: Characterization of Fiber Optic CMM Probe System

Abstract

This report documents a study completed on the fiber optic probe system that is a part of the Werth optical CMM. This study was necessary due to a lack of documentation from the vendor for the proper use and calibration of the fiber probe, and was performed in support of the Lithographie Galvanoformung Abformung (LIGA) development program at the FM&T. As a result of this study, a better understanding of the fiber optic probe has been developed, including guidelines for its proper use and calibration.

  • This report documents the results of Phase I research into a new type of Fiber Optic Current probe, suitable for high voltage, high current applications. The probe uses a stabilized two frequency HeNe laser to read the magnitude and sign of magnetic field induced circular birefringence in an optical fiber wound around a conductor. Measurements of both alternating and direct currents were demonstrated with a breadboard system. The system was tested at low voltages with currents of up to 4500 amperes peak and with up to 28 turns of optical fiber around the conductor. The response was found to increasemore » linearly with the number of fiber turns. Experimental determinations of the system's frequency response and dynamic range were not possible due to our inability to generate large, fast current transients. The predicted frequency response is 100 kHz with an ability to read transient amplitudes of 300 times the nominal line current. Several single-mode fibers were used to form transducers, and the optimum fiber for further development was identified. The 2-frequency interrogation technique described worked entirely as predicted, and should be applicable to magnetic field measurements in general (i.e. charged particle beams, Tokamaks, antenna patterns, EMP testing, etc.).« less
  • In 1995, a challenge in the field of genetics dealt with the acquisition of efficient DNA sequencing techniques for reading the 3 billion base-pairs that comprised the human genome. AccuPhotonics, Inc. proposed to develop and manufacture a state-of-the-art near-field scanning optical microscopy (NSOM) fiber-optic probe that was expected to increase probe efficiency by two orders of magnitude over the existing state-of-the-art and to improve resolution to 10Å. The detailed design calculation and optimization of electrical properties of the fiber-optic probe tip geometry would be performed at LLNL, using existing finite-difference time-domain (FDTD) electromagnetic (EM) codes.
  • The National Communications System (NCS) is responsible for defining reasonable enhancements that could be applied to commercial common carrier (or carriers'- carrier) fiber-optic systems that will be leased or owned by government agencies and which may be used for National Security/Emergency Preparedness (NSEP) purposes. This report provides background excerpted from many references used in the development of a multitier specification that identifies five levels of enhancement. (The multitier specification is presented in a separate report.) The report describes the nuclear environment for surface and in-atmosphere bursts outside of the blast region, where buildings and personnel would be expected to survive.more » In the environment, the vulnerability of optical fiber waveguides to fallout radiation is a primary concern. An assessment of fiber darkening, based on a review of unclassified literature, is presented. For exo-atmospheric nuclear bursts, the fiber optic system is exposed to High Altitude electromagnetic pulse (HEMP) radiation. Unclassified levels of these nuclear effects have been obtained from published literature. The characteristics of future generations of optical-fiber systems, as described in current literature, are outlined.« less
  • Brookhaven National Laboratory (BNL) recently developed a two-component system for use during remote inspections. The system consists of a mobile unit with television cameras and other equipment and a stationary base station. A variety of signals must be continually transmitted between the two system components as the mobile unit is moved from the location to another. Two channels of broadband (10MHz) NTSC video are transmitted from the mobile unit to the base station, and a bi-directional ``talk set`` provides audio communication between personnel at each location. In addition, several channels of RS-232 are required to support present and future instrumentsmore » used at the mobile unit and controlled by personnel at the base station. Brookhaven developed a mobile unit which communicated with a base station over a 2-fiber multimode fiber optic cable. One of the design requirements was maintaining constant communication with the base station during the time the mobile unit was moved about. To provide uninterrupted communications, deployment of the 1-km long fiber optic cable was initially performed with a ``spinning reel`` mechanism. The spinning reel mechanism proved to be mechanically unsuitable, and so the cable deployment mechanism was redesigned to spool the cable off the reel. The requirement for uninterrupted communications required a two-channel fiber optic rotary joint in the design. Incorporation of the rotary joint into the design is described, and appropriate reference material is included.« less
