  • Method and device for non-destructive inspection of objects by means of optical holographic interferometry
    Patent number: 6522409
    Abstract: This invention relates to a method and device for non-destructive inspection by means of holographic interferometry of details, machine units, mechanisms, and various materials, which eliminates the problem of relative displacement of the object with regard to the holographic equipment, especially due to vibratory motion of the object. This is achieved by transporting the reference and object beams between the investigated object, light source, and interferometer in flexible wave guidance cables and that the endpoints of the flexible wave guidance cables are securely attached in a fixed distance from the investigated object, recording medium of the interferometer and light source, respectively. This will also give the benefit of dividing the holographic interferometer into an object part and a registering part which forms the interferograms.
