  • Holographic recording instrument for structural integrity verification and other applications
    Patent number: 4084427
    Abstract: An improved holographic recording instrument for recording on a holographic recording medium two successive holograms of the structure under differing stress conditions to produce a holographic interferogram containing information defining a deformation fringe pattern representing the deformations in the structure resulting from the change in stress conditions. A holographic recording unit for the instrument and for general holographic recording use.
    Type: Grant
    Filed: October 29, 1976
    Date of Patent: April 18, 1978
    Assignee: TRW Inc.
    Inventors: Jerold L. Jacoby, William S. Tierney, James E. Wright, Pravin G. Bhuta
  • Pulsed holographic system having independent universal beam adjustment
    Patent number: 4049336
    Abstract: An improved holographic instrument for evaluating the structural integrity of a load-bearing structure by recording on a holographic recording medium two successive holograms of the structure under differing stress conditions to produce a holographic interferogram containing information defining a deformation fringe pattern representing the deformations in the structure resulting from the change in stress conditions. A holographic recording unit for the optical signature instrument and for general holographic recording use.

    Date of Patent: September 20, 1977
    Assignee: TRW Inc.
    Inventors: Jerold L. Jacoby, William S. Tierney, James E. Wright, Pravin G. Bhuta
  • Holographic instrument for measuring stress in a borehole wall
    Patent number: 3960448
    Abstract: An instrument for determining the stress in the wall of a borehole by recording successively on the same holographic recording medium two holograms of a selected surface region of the wall, and, in the interval between the two recordings, forming a stress relief in the wall in stress relieving relation to the surface region to produce on the recording medium a double exposure hologram. This hologram contains holographic information which represents the stress in the wall in the vicinity of the surface region and may be converted to data defining the magnitude and direction of the stress.
