  • 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.

  • 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.
    Type: Grant

  • Patent number: 4019374
    Abstract: An impulser for percussively loading a structure to generate stress waves in the structure by driving a hammer into impact relation with the structure and generating an electrical signal in timed relation to the impact. The impulser may embody means, such as suction cups, for firmly attaching the impulser to the structure and an anvil which is interposed between the hammer and structure and spring loaded against the structure for transmitting the hammer impact to the structure without damaging the structure.
