Copying and mass production[ edit ] An existing hologram can be copied by embossing [37] or optically. Embossing, which is similar to the method used to stamp out plastic discs from a master in audio recording, involves copying this surface relief pattern by impressing it onto another material.

The first step in the embossing process is to make a stamper by electrodeposition of nickel on the relief image recorded on the photoresist or photothermoplastic. When the nickel layer is thick enough, it is separated from the master hologram and mounted on a metal backing plate.

The material used to make embossed copies consists of a polyester base film, a resin separation layer and a thermoplastic film constituting the holographic layer. The embossing process can be carried out with a simple heated press. The bottom layer of the duplicating film the thermoplastic layer is heated above its softening point and pressed against the stamper, so that it takes up its shape.

This shape is retained when the film is cooled and removed from the press. In order to permit the viewing of embossed holograms in reflection, an additional reflecting layer of aluminum is usually added on the hologram recording layer.

This method is particularly suited to mass production. This featured a 5. On the inner sleeve was an explanation of the holographic process and instructions on how to light the hologram and National Geographic published the first magazine with a hologram cover in March Stability and coherence requirements are significantly reduced if the two plates are located very close together.

Uniform illumination can be obtained by scanning point-by-point or with a beam shaped into a thin line. Reconstructing and viewing the holographic image[ edit ] Holographic self-portrait, exhibited at the National Polytechnic Museum, Sofia When the hologram plate is illuminated by a laser beam identical to the reference beam which was used to record the hologram, an exact reconstruction of the original object wavefront is obtained.

An imaging system an eye or a camera located in the reconstructed beam 'sees' exactly the same scene as it would have done when viewing the original. When the lens is moved, the image changes in the same way as it would have done when the object was in place.

If several objects were present when the hologram was recorded, the reconstructed objects move relative to one another, i. It was very common in the early days of holography to use a chess board as the object and then take photographs at several different angles using the reconstructed light to show how the relative positions of the chess pieces appeared to change.

A holographic image can also be obtained using a different laser beam configuration to the original recording object beam, but the reconstructed image will not match the original exactly.

This can be a major drawback in viewing a hologram. White light consists of light of a wide range of wavelengths. Normally, if a hologram is illuminated by a white light source, each wavelength can be considered to generate its own holographic reconstruction, and these will vary in size, angle, and distance.

These will be superimposed, and the summed image will wipe out any information about the original scene, as if superimposing a set of photographs of the same object of different sizes and orientations. However, a holographic image can be obtained using white light in specific circumstances, e.

The white light source used to view these holograms should always approximate to a point source, i.

An extended source e. White light reconstructions do not contain speckles. Volume hologram A reflection-type volume hologram can give an acceptably clear reconstructed image using a white light source, as the hologram structure itself effectively filters out light of wavelengths outside a relatively narrow range.

In theory, the result should be an image of approximately the same colour as the laser light used to make the hologram.Last updated: 26 October About This Manual.

This is version of the manual to the home and professional versions of X‑Plane (X-Plane 11 and X‑Plane 11 for Professional Use, respectively). Introduction. A delightful experience with rare flavor awaits one who beholds a celestial wonder with a mirror crafted with his or her hands.

Most persons making their first telescope mirror also find another kind of rare flavor in the experience: the reward of meeting a challenge that requires discipline and concentration of one's mental faculties. SpaceX Finalizes $M Loan (Source: Wall Street Journal) SpaceX has raised $ million in a new loan.

Images in a plane mirror are the same size as the object, are located behind the mirror, and are oriented in the same direction as the object (i.e., “upright”). \n.
