It is 3D because the new light wave becomes modified by the wave-interference pattern recorded in the emulsion and appears thereby as the original light wave emitted by the object itself.ĥ) When the light wave hits the Master holographic medium and reflects from this film, this will contain the information originally recorded, multiplied by the intensity of the new light beam. However, unlike a photographic image, it is the interaction of the new light wave with the recorded interference pattern that is seen as a 3D image. All these different scenes can be called up, by aiming a laser beam on the photographic film, under the same angle as the reference beam that was being used.Ģ) When you create a cylindrical hologram, you can see the original 3D object in a 360 degree view.ģ) You can copy the Master hologram with the reference beam reflecting from the Master on a new photographic film and the result will be a positive image, exactly the same as the image produced by the original Master.Ĥ) When a light wave hits the Master holographic film, it acts as a (diffractive) filter, allowing some light to pass through and pick up the imprint in the medium. It depends on the angle under which the reference beam hits the film and creates the interference pattern with the object beam. MAIMAN had produced the first laser, then the stage was set for the production of the first three-dimensional images and in 1960 the researchers LEITH and UPATNIEKS of the University of Michigan created the first off-axis laser transmission holograms followed around the same time by Yuri DENISYUK of the Soviet Union, who created reflection holograms that one could see using ordinary white light.ġ) On the same holographic (photographic) film one can record multiple scenes, images of 3D objects, on the not yet developed film. This also means that a laser beam has a precise mathematical property and can carry a large amount of intelligent information. In laser technology, COHERENT LIGHT denotes a light source that produces light waves of IDENTICAL FREQUENCY, PHASE and POLARIZATION. The emitted LASER light is usually a spatially COHERENT, narrow low-divergence beam, which can be manipulated with lenses (like in holography). This is a process for emitting electromagnetic radiation, typically light or visible light, via the process of stimulated emission. LASER means: Light Amplification by Stimulated Emission of Radiation. Maiman later received also a Nobel Prize for Physics, together with Townes and Schawlow, for the development of the laser theory in 1958 (see figure 1 and figure 2). In May of 1960 THEODORE MAIMAN at Hughes research Laboratories built the first laser, pulses of red light coming from a ruby cylinder that was put inside a very bright flash lamp with a helical shape. In 1947 coherent light sources were not available, and the conventional light sources generally provided too little light, or light that was too diffuse to obtain good results (DISPERSION of the light used). In this manner a complete holo-spatial picture can be obtained. The basic idea was, that for perfect optical imaging, the total of all the information has to be used, which means, not only the amplitude of the light-wave as in usual optical imaging, but also the phase.
He developed the idea of holography in 1947, while working on improving the electron microscope. The inventor of holography was a Hungarian-born electrical engineer DENNIS GABOR, who won the Nobel Prize for Physics in 1971 for his invention. The playback provides an image in light that can be viewed in different angles and is an exact copy of the original 3D object. Holography is a technique, which allows the recording and playback of true three-dimensional images. -Presentation: The Holographic Experience.-Sudarium of Oviedo Janice Bennet Bennett.-Isabel Piczek Article THE EVENT HORIZON.-Making of the Sculpture of Jesus Christ.-Research Nails, Phylacterie, Lance, Leptons.-VP-8 Image Analyzer and Set-up Research 3D.-Holography and the creation of the Master.-Conversion process of 2D to 3D and The Gray Scale.-Digitization of the photographic material.-Photographic material – Giuseppe Enrie.-Holographic Observations in the Shroud Image (Holographic Theory).-3D Studies of the Shroud of Turin (history).-Image Qualities of the Shroud of Turin.
