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 laser beam sources positioned within the structure to form a laser reference beam and laser object beam 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.
