摘要： This invention relates to the field of holography, in particular to a method and a device for recording optical holograms by means of amorphous molecular semiconductor (AMS) films deposited on a glass substrate pre-covered with a transparent electric conducting sub-layer. More precisely, the invention relates to a method and device for registering optical holograms on AMS-films which operates in such a way that the AMS-films possess the maximum achievable information parameters: Holographic sensitivity, optimal spatial frequency of the transmitted characteristic, band parameters for the spatial frequencies of the transmitted characteristic, “signal-to-noise” ratio in the restored holographic image, reference and object beam intensities ratio during hologram registration, and cycling ability. It is also an advantage that the device provides optimal operation efficiency of the registering media based on AMS-films, and restricts the development and erasing of the hologram upon reaching the pre-set value of the diffraction efficiency measured in the zeroth order of diffraction. The latter makes the device a universal device.

摘要： This invention relates to a method and device for non-destructive testing of details, machine units and mechanisms, various materials, and in particular, to a method and device for non-destructive determination of residual stresses which are based on the optical holographic interferometry technique. First, a hologram of the investigation area of the object in its initial state is registered. Then the release of the residual stresses in an investigation point in the investigation area is performed by exposing the surface of the object to a high-current electric pulse with rectangular shape. Finally, an interferogram of the exact same area of the object is made, and the residual stresses at the investigation area are determined from the shape and size of the fringes in the interferogram.

摘要： This invention relates to the photo-sensitive thermoplastic top-layer of optical media for registration of holograms, where the media consists of three transparent layers where the bottom layer is a glass substrate, the mid layer is an electro-conductive film of tin dioxide, and the top layer is a thermoplastic photo-sensitive amorphous molecular semiconductor film made of a matrix which has donor properties and forms transport bands for holes, and were the matrix is doped with; a photo-sensitive substance (CICT) that has intramolecular physically separated parts with donor and acceptor properties, respectively, and which creates an intramolecular electron-hole pair when absorbing a light quantum, and which has a HOMO-level which is below the HOMO-level of the matrix substance, and a substance with acceptor properties that forms transport bands for electrons, which has a similar ring structure as the acceptor part of CICT to ensure a barrierless transfer of excited electrons from CICT to acceptor-molecules and which has attached a large hydrocarbon chain in order to enhance the plasticity of the film and to provide steric hindrance for the formation charge transfer complexes between acceptor and matrix molecules.

摘要： This invention relates to a method and device for performing non-destructive measurements of residual stresses in an investigation area of an object based on use of optical holographic interferometry technique. The holographic interferometer is divided into a holographic probe which contains means for illuminating the investigation area of the object by coherent light, collecting the coherent light that scatters off this investigation area and means for performing a non-destructive dislocation release pulse of the residual stresses in a small region of the investigation area by exposing the object to an electric high currency, and a holographic camera which contains means for formation, registration, and development of a hologram and for formation of an interferogram of the investigation area of the object. The object coherent light is sent from the light source to the probe by a single-mode light guidance cable, from the probe to the holographic camera by an other single-mode light guidance cable, and the reference coherent light from the light source to the holographic camera in a third single-mode light guidance cable. In this way, one is allowed to measure residual stresses on surfaces of an object with high curvatures, in hardly accessible places, and under many weather conditions by a simple hand-held manual positioning of the holographic probe during the measurements.

摘要： 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. Thus it becomes possible to perform measurements on objects in situ under any weather condition while the sensitive recording equipment of the holographic interferometer can be operated in a distant protected location.
