pattern of interference. The interference pattern is made possible by the properties of light generated by a LASER.” (www.holoworld.com/holo/quest2) In order to have a hologram be effective and accurate it needs two things: 1.Light needs to be highly directional2.One colorIf it is done correctly your eyes and brain perceives the object as being in front of you. Basically it is a mind trick.Earlier I mentioned holography. This is a method that allows the “recording and playback of true-three dimensional images.” (www.holoworld.com/holo/quest1) Holograms posses an effect unlike other 3D images. This is known as “parallax.” “Parallax allows the viewer to move back and forth, up and down, and see different perspectives”(www.holoworld.com/holo/quest1) Dr. Dennis Gabor, Imperial College of London invented holography. In 1971 he received the Nobel Prize in physics for holography. Although, round the world, holographic images and techniques are constantly being improved upon. Still holography has proved to be the most accurate interpretation of three-dimensional images in the world.Holograms are made be using a LASER light. Did you know that LASER is actually an acronym that stands for Light Amplification by Stimulated Emissions of Radiation? Anyway, a LASER is a special source of light that was invented in the early 60’s. Generally, A laser is a very thin glass tube, about the size of a straw that you use to drink a soda. In the glass tube there is gas, most commonly it is Helium and Neon. There are several different sizes, brands, and types of LASERS. LASERS are used in a variety of fields such as medical, scientists, jewelry makers, appliances, etc“Laser’s produce light that has very special characteristics: first the light is monochromic, or a single wavelength/color. Second, the light from a LASER is coherent, which means it has all of its waves traveling in sync wit...
