   Security Holography
   
   Holograms cannot be duplicated through photocopying or computer scanning. If you are looking for a security application of holography, Holographic Studios can create a hologram for you. We have delivered millions of security holograms. These holograms have been used for anti-counterfeiting, tamper evidence, and authentification. We have years of experience in this field. Some of the specialty feature that we can incorporate into a hologram are uniquely mastered images, sequential numbering, tamper evident foils, covert imaging, and multiple channels. Among our security holography clients are Singer, Eicher, and Authenticorp.

   Computer Generated Holography
   Holographic Studios can transfer your 3D computer generated images into an actual three dimensional holography displays. Imagine seeing your 3D images in true holographic dimentionality!
   
   We use a series of images of an object either rotating or being moved laterally along the horizontal axis. Our preference is to work from standard digital image files, but if necessary we can adapt to your format. Each two dimensional image is shot as a sequential hologram strip on our Integral Holographic Printer that combines these images into a single three dimensional hologram.
   
   Among our computer generated holography clients are NYU Medical Center, Mitsubishi, The American Museum of Natural History, Michigan State University, and Allied.

5. HOLOGRAPHY FOR KIDS

   Hi Kids!
   
   I'm Doctor Laser! My real name is Jason Sapan. My first job working in holography was in 1968. Its been exciting working with lasers in a laboratory all these years. I'd like to share some of what I've learned with you.
   
   Holography is unlike any other way of making a picture. Holograms are 3D. That means that holograms are three dimensional. Photographs are two dimensional or as we say, flat! The two dimensions in a photograph are width and height. Holograms have both of these plus the third dimension, depth (another way of saying thickness). Everything around us has all three of these dimensions, even you!
   
   Did you know it takes two eyes to see in 3D? Its true! Its because the field of vision of each eye overlaps the other that we can see in three dimensions. Your brain can tell from the slight differences in position of where each of your eyes is looking, where in 3D space the thing you are looking at actually is. Try covering one eye and then reaching out to grab something. Its hard. That's because we need 3D vision to be able to judge where things are.
   
   Holograms are not the only type of 3D picture. They are just the best! That's because holograms are very powerful. If you made a hologram of a leaf with a droplet of water on it, you could take a microscope to the hologram and see what's in that drop of water, like the nucleus of a one celled amoeba! That's because holograms store details down to the size of light waves. And light waves are truly itsy bitsy. Light waves measure about a half of a millionth of a meter in size. You could fit around two million light waves in a meter. A meter is the standard metric measurement and is 39.37 inches long, just a few inches longer than a yard. In a hologram everything down to size of a light wave is recorded. Its a very powerful medium. A hologram the size of an average man's brain could store every written document in history from the ancient days of Hammurabi's Code in Mesopotania to today's newspaper. Now that's powerful!
   
   How A Hologram Works
   
   Holograms are made by bouncing laser light off an object. When the wave of light hits the object, its just like taking a piece of modelling clay and pressing it up against that object. It takes the shape of the object. Once it has taken the shape it bounces off and onto a piece of photographic film. Just like the film that is used in a disposable camera, but much more able to capture even the tiniest details. Film captures images by recording where light hits it. So, what is film?
   
   Film is made of a clear piece of plastic covered with gelatin (just like clear jello with no flavor). Inside the gelatin are grains of silver iodide (sometimes called silver halide). These grains are light sensitive. When light waves hit these grains, it gives them energy. Just like the light energy was pulling it open in the same way someone might pull open a bear trap. The exposed film is put in a bath of a liquid chemical called developer. The silver halide grains that have been exposed to light, grab on to oxygen in the developer chemicals. When a silver based chemical mixes with oxygen it turns black. Your Mom can tell you how her silver jewelry tarnishes. Tarnish is the word people use to describe the way silver turns black when oxygen mixes with it. Holographic film can capture details thousands of times smaller than regular film. That's because the grains of silver halide in regular photographic film are much bigger than the grains in holographic film. Its like the difference in size of the grains of table sugar compared to the powder fine grains of confectioner's sugar that coats a powdered sugar donut. The name for this ability to record fine details in film is called resolution. The smaller the size of the grains the better the resolution. We need this ultra fine resolution in holography because our pictures are of microscopic light wave patterns. Its a lot like having a real lot of pixels in a digital camera. The more pixels, the more detail.
   
   But there's another step in making holograms. And its a very important one. We need to make the light waves stand still in order to take their picture. The method we use is called Interference.
   
   According to one of the smartest scientist who ever lived, Albert Einstein, light is the fastest moving thing in the universe. Now, this poses a problem. How do you take a picture of something moving that fast? I'm sure you have taken pictures of someone moving that have come out blurry. And they were moving much slower than light speed. So, how is it done?
   
   Light travels in waves. Just like waves in the ocean. All waves behave the same. When waves meet in the ocean, they cross paths. You might say that as the waves cross, they interfere with one another. Imagine yourself standing on a small bridge over a pond with Albert Einstein. He might have suggested that both of you drop a small stone into the water at the same time. As the stones hit the water they spash and make circular waves that spread out. Soon the two circular waves meet and cross over each other. In time the waves pass each other and continue moving on their merry way. But what we're interested in is the area in which they meet and interfere. Something special happens there. The pattern of interfering waves stand still! So lets try to understand why this happens.
   
   Think of the way a wave looks in the water. Its got a high point and then a low point. You might say its got a bump in it. When one wave travels over another wave it has to leap frog over the bumps it sees in the other wave. The bumps are like what happens when a river has to leap frog over big boulders in its path. You see big white water sometimes called rapids. From the side of the river these rapids look like bumps in the swiftly running water. The water is moving through the bump, but the bump stays in the same place. It stands still. Scientists call a wave that stands still a standing wave. So, whenever waves interfere, each wave sees the other in the same way the water in a river sees the boulders in its bed. Its a series of bumps it leap frogs over and creates standing waves. And since the waves stand still, we can take a photgraph of them. We call this photograph of standing waves a hologram.

   Holographic Studios is a full service custom holography lab.  We make a wide range of holograms to meet your specific needs.  From annual report covers to large scale displays we've been doing it for over thirty years.  We can make a one of a kind or mass produced run of holograms.  With our many years of experienced we can help you optimize this exciting medium to create attention.
   
   Holographic Studios is one of the only holography labs in the world specializing in true full motion image Integral Holography. It is a multi step process. Images are first shot on 16mm or 35mm motion picture film, video, or computer generated, and then transferred with a laser to hologram film. Integral Holograms can be displayed flat, curved, or as a cylinder viewable from 360 degrees. Displaying the hologram on a curved or cylindrical surface makes the hologram viewable to a larger audience than normal. Integral Holograms can be created from:
   
   * living people in motion
   * moving machine parts
   * chemical or biological models stationary or in motion
   * stop motion animation
   * video
   * computer generated imagry
   * special effects such as morphs, dissolves, zooms, etc.
   
   We can produce both the master hologram and scanned copy holograms right here in our laboratories. Because Integral Holograms are made in a two step process, we can shoot the original film wherever you want. There are no size or motion limitations! We can blow up or shrink the image to whatever size is necessary! Although we prefer to do our original cinematography here at our studios, many of our projects have been filmed on site at remote locations. Over the decades we have created Integral Holograms for corporate clients including Comet Systems, G.D.Searle, Squibb, TDK, Celanese, Certainteed, American Enka, Talon, ICI, DuPont, Hasbro, The Philadelphia Stock Market, Shaw/Walker, Remy Martin, Hyatt, Lord & Taylor,and the U.S. Army.
   
   You can rent our Integral Holograms for special events!
