ABSTRACT:
A method and apparatus are provided for the holographic examination of the internal features of cavities and passageways of a structure. The apparatus employs a laser beam source positioned external of the structure coupled to a multilayer fiber waveguide which conveys the reference beam and object beam, in at least two different layers of the multilayer fiber, which combine in a holographic recordation means to form a hologram of the internal features of the structure, or under certain circumstances a holographic interferogram of the selected features is formed.
