Paper Abstract

A new method of holographic recording in the form of a thin laser beam which moves consecutively parallel to itself is being discussed which gives the scanning of all the space which is being holographed (object+hologram). Such a recording has been experimentally carried out in a single-beam scheme after the method of reflective holography and the technique of receiving large- sized holograms of scenes of a sufficiently large size has been improved. The production of higheffective reflective holograms on bihromate gelatine has been discussed a new technology of heat treatment has been proposed and an experimental check has been carried out. Gabor studying the ways which help us to improve the resolving power of an electron microscope created a new holographic method of an optical image. In particular while illuminating an object by a coherent light wave (the greatest part of'' the wave Is supposed to penetrate the object without disturbance) the diffraction image formed as a result of the secondary wave interference which appear in the presence of an object with a strong reference wave is recorded on a photographic plate. The reference wave transforms phase differences into intensity differences that is the phase turns out to be encoded in the quantity which is recorded on a photographic plate. In 1962W 1964 E. Leit and U. Upatnieks substantially improved Gabor''s method by using2 a laser and the off-axis recording scheme.
