Abstract: 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.

Abstract: 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.
