Ans - A Hologram is a physical structure that diffracts light into an image. The term ‘Hologram” can be referred to both the encoded material and the resulting image.
Ans - A Holographic image can be seen by looking into an illuminated holographic print or by shinning a laser through a hologram and projecting the image on a screen.
Ans - Holography is based on principle of interference. A hologram captures the interference between two or more beams of coherent light, i.e., laser lights. One beam is shown directly on the recording medium and acts as a reference to the light scattered on the illuminated screen.
Ans - 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. When a laser is used to reconstruct the hologram, the image is speckled just as the original image will have been.
Ans - A hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holograph subject, which is seen without the aid of special glasses or other intermediate optics.
Ans - The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a boundary to the region, preferably a light-like boundary like a gravitational horizon.
Ans - Hologram is very difficult to copy. Generally what passes as copies of holograms are not holograms at all, but diffractive material with screen printing and or hot stamping with various foils. To the untrained eye they appear like holograms because they have some form of rainbow colors.
Ans - Holography is a photographic technique that records the light scattered from an object, and then presents it in a way that appears three-dimensional.
Ans - A lot of work is currently going into creating 3D holograms that can be seen by the naked eye without wearing 3D glasses, and now researchers have found a way to make safe, touchable mid-air displays using fem to second lasers.
Ans - Security holograms stickers are labels with a hologram printed onto it for sale security reasons. Security holograms are very difficult to forge because they are replicated from a master hologram which requires expensive, specialized and technologically advanced equipment.
Ans - A holographic display is a type of display that utilizes light diffraction to create a virtual three-dimensional image of an object. Holographic displays are unique from other forms of 3D imaging in that they do not require the aid of any special glasses or external equipment for a viewer to see the image.
Ans - An astonishing theory called the holographic principle holds that the universe is like a hologram: just as a trick of light allows a fully three-dimensional image to be recorded on a flat piece of film, our seemingly three-dimensional universe could be completely equivalent to alternative quantum fields and physical appearance.
Ans - Holograms are available in many varieties. They are 2D holograms, 3D holograms, dot matrix holograms, E-beam holograms, flip flop holograms, kinetic movement holograms, micro text holograms, image in holograms. Holograms are also available on many surface varieties with different colors. Holograms are available in silver, gold, copper, pink, green, multi colored surfaces. Latest addition is Barcode labels, Shrink labels, Real Photo Holograms and many such more.
Ans - Holograms have 3D holographic visual effects. Holograms or holographic labels when put to an ordinary light or laser beam exposure it exhibits distinct hologram properties. A hologram displays the inscriptions in prismatic effect. This prismatic display of holograms is security symbols. This holographic seal certifies the authenticity of the product, service or document. Therefore, holograms are a guarantee against duplicity, counterfeit production. Holograms itself cannot be copied, duplicated or tampered.
Ans - Master is the final artwork of the desired hologram the users intend to use. Master of any hologram, holographic sticker, holographic seal or holographic label is prepared for one time only. Repeat manufacturing of holograms does not need require repeat production of master for the holograms.
Ans - Holograms are the most effective method of recording serial numbers. Holographic serial numbers can easily be recorded in products, services or documents. Holographic serial numbers are beyond tampering. This makes holograms. The most authenticate security serial number system.
