Paper Abstract

Superposed holographic interferometers1'2 are designed to investigate the displacement and deformation of the plane parts of the surface of the diffuse objects. These interferometers can register the information about the displacement of the points of the deformed surface relative to any base of the interferometer during the experiment staying practically stable because of using low modular optically transparent medium between the base of the interferometer and deformed surface. The problem appears in those cases when the thin wall construction is to be investigating of supporting the walls of construction by interferometer itself. This problem were solved by means of using the low inertial adaptive base interferometer in which were registered the information about the additional difference step arising because of angles of illumination variation in difference with former used methods of getting of information. This method allow us to construct the optical transformer in laboratory conditions separately in terms of gelatine emulsion or film and then to place their on the object's surface for the aim of control of the deformation of the objects. The interferogram may be observed as in white as well as in monochromatic light It contain in itself the information about curvature of the surface relative to basic one registered in laboratoiy conditions. The caving in process of the construction is followed by change of angle of illumination and hence is followed be change of sight of interference fringes. The structural differences of the hologram contain the information about the curvature change variation of the surface researched.
