Abstract

A METHOD FOR OBTAINING A SURROUNDED HOLOGRAPHIC IMAGE by recording a hologram of an object and restoring a real image in space, into the region of which a pre-heated photosensitive medium is interfered with in the form of a three-dimensional block, which is a heterogeneous mixture of at least two components — solvent and particles, and interact with it external force field, which is distinguished by the fact that, in order to increase the visual zone, the volume image recorded on the carrier is re-holographic a holographic screen comprising a layer of a heterogeneous mixture, wherein the screen area of at least two seconds and the order of greater than the original area of the hologram, and reduced screen (A three-dimensional image.

On it i2 the hologram recordings in the area of the plates 5 create a uniform magnetic field. For the next time, SCHYUZYVOD5GG reconstructs the displayed three-dimensional image from the holography recorded and fixed on the large plate-screen 5. The same time interval i produces the recorded three-dimensional images on the volume carrier 3. In the subsequent period of time i, the volume carrier 3 records a volume image reconstructed from the entire frame of the next frame on film 1 and one & With this, they erase the big gkhologram from the large plate of the screen 5 on the first frame of the film, etc. Example 1 To implement the proposed method, an amount of photosensitive optically reversible carrier is used containing a heterogeneous mixture in which the dispersion medium (solvent) is paraffin and the particles are ferromagnetic (for example). The magnetic field is magnetic. For such a medium, the time of one recording cycle (recording, fixing, washing) is 1O s (4) and, therefore, such a carrier is quite suitable for the demonstration method: holographic cinema .., With the help of laser 3 of the same wavelength, holography of the film (for example, red with colors (I 0, 63 µm)), during the time t 20 ms, a three-dimensional image is restored from the hologram frame. During this time i record the reconstructed image on a three-dimensional block of a carrier in a transparent cell - the idea of a rectangular pair For this, a uniform magnetic field is created for the recording time in the block area. At the next i-2-2O ms time using another more powerful laser 4, the KGG recording recorded on the carrier is -2 a three-dimensional image on a large plate 5 with a photosensitive layer and a hologram is recorded on this plate. frames on film 1 movie. At time t2, the holograms on plate 5 in the region of this plate create a uniform magnetic field. For the next 13-2O ms esek time, laser 4 restores the three-dimensional image shown from a large hologram 5, EXAMPLE 2. The proposed method of demonstrating a holographic film is carried out analogously to example 1, but using a heterogeneous optical carrier. the mixture in which the dispersion medium (solvent) is paraffin, the particles are ferroelectric (, BaTyO.) -, the force field is electric. The proposed method makes it possible to solve the problem of a large screen in volumetric holographic cinema and thereby implement a theatrical (for a large number of viewers) holographic cinema with a three-dimensional image.
