Making your own hologram can seem like an impossibly complicated task, but with the aid of a few tools, it is actually a simple process. A hologram is a 3D image made using special film and a laser. Using a specialized kit, a hologram can be made in the comfort of your home. Hologram kits are available from a variety of places online (see Resources)


 

Instructions
    • 1
      Choose an object. A good choice of object is integral to getting a good holographic image. Choose something hard, with defined edges. It can`t be made of fabric, and reflective material is beneficial. Metal items produce good holograms, as long as the surface reflects light well. Hologram-making is a lot like photography, but with lasers for light and a sturdy, sticky film.
    • 2
      Find a sturdy table to create your hologram. Any movement during the process of making a hologram can ruin the picture. This will become more evident the further into the process you get, but for now, find a sturdy surface to use. Ensure that the room has curtains so light can be blocked out later. The room has to be too dark for reading during the image-capturing.
    • 3
      Place the object on the table. The laser will have to be about a foot away from the object, so ensure that there is enough space for it to be placed on your surface. Sit it on something like a mouse pad or small box of sand (or salt or sugar granules) to ensure stability.
    • 4
      Take your laser out and switch it on. Set the laser to spread its beam, or take off the lens if you can. Lasers included in hologram kits will do this easily. Point it at the object, a foot (or slightly farther) away. Dim the lights if you can`t make out how well illuminated it is. You want to get the best light coverage you can, so take your time. The spread of light is elliptical, so it can be difficult to center.
    • 5
      Stand up a large hardback book between the laser and the object. The book should be large enough to shield the object from laser-beam light. This is the equivalent of a shutter on a camera.
    • 6
      Ensure that the room is dark and take out the holographic film plate. Handle the plate carefully, and read the instructions the came with it before use. Take it out in the darkest spot in the room. This is like camera film, so any unwanted light could ruin the image. Carefully lay the sticky side of the plate onto your object. The plate will be tilted at a diagonal angle. Make sure that it is completely stable.
    • 7
      Lift the book slightly, but still block the laser-beam light. Wait a couple of seconds for the table to stop vibrating, and then completely lift the book, exposing the film and object to the spread of laser light. Wait between 10 and 40 seconds, ensuring that no one in the room moves or talks, causing unnecessary vibration. Replace the book.
    • 8
      Process the film as directed on the product`s instruction manual. Once the image is dried, the plate will display your hologram.
Tips & Warnings
  • Do not look directly into the laser` follow the safety precautions carefully.

A hologram is an illusion made using a source image and a light source to make a picture appear three-dimensional. If you have a TV, then you already have the main tool needed to make a convincing hologram



 

 

 

Instructions
  1. Create a Hologram
    • 1
      Set up your DVD or VHS to pause on a still image or play the movie on repeat. If you use a still image, you can control the appearance of the hologram at all times. If you use a short movie, you can create a moving hologram that will give the illusion of three-dimensional life. But the hologram may `skip` when the movie rewinds or goes back to the beginning
    • 2
      Clean the piece of glass with a lintless cloth so no streaks or dust are visible to break the illusion. For best results, use dry cleaning fluid so the glass displays virtually no reflection
    • 3
      Project your TV screen at the glass or Plexiglass. For best results, keep the TV out of sight by laying it flat behind a shelf or similar object, with the screen facing the ceiling and the glass angled at 45 degrees
    • 4
      Adjust the TV`s brightness as low as possible and the contrast as high as possible without distorting the picture. This will enhance the three-dimensional effect of the hologram
    • 5
      Turn on the movie and the TV and enjoy your hologram
Tips & Warnings
  • Your hologram will appear most vivid in the dark or at night
  • You can also use a computer monitor (LCD, or liquid crystal display), instead of a TV monitor (cathode ray tube, or CRT)
  • For added effect, include sound with your movie

Making a hologram is a simple procedure that makes anyone look like a professional. The process is easy to do but requires the right tools that can be purchased from a hobby supply store as well as items found around the house. Once you have the right tools, you are about an hour away from making amazing art concepts on paper

Instructions
    • 1
      Keep the film plate in the box. Place the object on the floor. Fill the soda can with sand
    • 2
      Secure the clothes pin on the diode. Place this in the sand to stand securely in place.
    • 3
      Remove the adjustable lens on the diode and point it at the object. Turn off all lights
    • 4
      Balance the cardboard in up against the diode, positioning it between the object and removing all illumination from it. This is the shutter that will "open" to expose the film plate
    • 5
      Remove the film plate from the box in the darkest possible area of the room, holding it with tongs.
    • 6
      Place a holographic plate with the tongs perpendicular to the ground against the object between it and the diode
    • 7
      Open the shutter by lifting the cardboard slowly and exposing the object through the film plate with the diode for ten seconds.
    • 8
      Replace the shutter in position, removing light from the object.
    • 9
      Follow instructions for holographic plate from the box it was purchased in, generally allowing it to soak in two solutions for several minutes, one after the other
    • 10
      Remove the plate with tongs and allow it to dry standing up
    • 11
      Peel the paper from the holographic plate
    • 12
      Shine natural light through at the hologram and look at it
       
Tips & Warnings
  • Always handle the holographic plate with the tongs
  • Never look directly into a laser diode

The word `hologram` comes from the Greek roots `holos` and`gramma,` meaning literally, `whole message.` Holograms, unlike conventional pictures, convey complete information about depth, shape and texture from many angles

History
  • Laser technology is the key to holography.
    Dennis Gabor developed the theory of holography in 1947, but the need for intense, focused light kept any holograms from being immediately produced. In 1962, four years after the invention of the laser, Emmett Leith and Juris Upatnieks produced the first holographic image
Method
  • A lens splits a laser into two beams. One beam (the `object beam`) illuminates the object being holographed, and the other (the `reference beam") points directly at holographic film. The object beam converges with the reference beam at the film, creating interference patterns that result in the holographic effect
In the Movies
  • The 3D image of Princess Leia from `Star Wars` was not a real hologram; it was a film effect. Holograms today cannot show moving images, and cannot project an image into open space
Pulsed Holography
  • The least movement during hologram capture will ruin the image. Pulsed holography, where the laser is activated for only a few nanoseconds, allows the capture of living people and other moving subjects
On Money
  • Embossed holograms are used on money and other documents to prevent counterfeiting. The holographic interference patterns are printed onto plastic and then backed with a light-reflecting foil. Embossed holograms can be mass produced very cheaply

A hologram is a pattern that is created through a photosensitive medium that is exposed to holography, then photographically developed to create a three-dimensional image to the human eye. This technology has offered artists and expressionists of today a vivid and special way to communicate a concept or idea to the public. Designing a hologram can be tricky, as these designs must be developed to reflect light in just the right way. Computer programs are needed to translate an image into a pattern that can be transformed into a hologram

Instructions
    • 1
      Start your design process using a computer program that works in layers, such as ImageReady, Photoshop or Corel Draw. These artwork programs allow you to design various layers of images that can be treated and turned into a hologram
    • 2
      Compose the background layer of the three layers. This background layer should contain only two colors. Make this layer simple and able to support the other layers in color and dimension
    • 3
      Design the foreground layer with three distinct colors that are different from the two background layer colors. This layer should have the bulk of your design concept on it. Save the file as a foreground layer as a JPG or GIF file
    • 4
      Finalize the design with a floating layer of your hologram image with one separate color, different from the other layers. There should be six distinct colors total among the three layers. Use the floating layer to add any special information you did not list in your foreground layer
    • 5
      Submit your design files to a professional firm that can treat the files to the processes necessary to make the image a hologram. Hologram artwork designs are an illusion. These images are simply reflections of light that fool the eye into seeing a three-dimensional image. It is impossible to give an accurate representation of a holographic image on a computer screen or paper printout, but the firm you use will verify your image integrity before it completes the process

Once the stuff of science fiction only, the hologram, a three-dimensional image, went from the`gosh-wow` phase to being so common they are used on credit cards and driver`s licenses. Yet they have failed so far to make the transition to the Princess Leia images from `Star Wars,` where the image stands by itself in the middle of a room

History
  • Nobel laureate Dennis Gabor created the first hologram in 1947, which led to his Nobel Prize in physics 24 years later. He actually discovered the effect while trying to make the then-new electron microscope better. While this discovery was patented, it wasn`t until Theodore Maiman or Gordon Gould created the first optical laser in the late 1950s or early 1960s, depending on which version of history you choose. The laser, which has a consistent light wavelength, gave the precision needed to make the hologram work
Function
  • Essentially, a laser beam is diffused through a`beam spreader` to give more light area without losing the single wavelength. Two such lasers are used to simulate what the human eye will see. For example, an apple is placed on a table. One laser is pointed directly at it, while the other is off to one side. This separation creates two images on the same photo plate at the same moment
Effects
  • The photo plate is developed, then printed, but not to ordinary photo paper. Instead, silver diffracting material is used. When viewed in white light, the image is a color rendition of the original object. The 3-D effect comes from the two slightly different angles at which both lasers were fired.
Types
  • Some common uses for holograms include the aforementioned credit cards and driver`s licenses as well as other identifying items. The reason is because it is difficult for forgers to duplicate them without high-tech equipment. A photograph can be easily replicated because the technology is readily available. It takes higher-level equipment than most people have in their homes to create holograms. The hologram in this case provides security for people and businesses
Significance
  • Holograms, in various forms, also can be used to get three-dimensional images of the insides of the human body or to navigate an airplane. The computed axial tomography (CAT) scan, for example, takes images of the human body so doctors can get a look at what`s wrong or right without having to perform surgery. Pilots can use the `heads-up` display to get specific landing numbers such as distance and elevation by looking at a hologram projected in the cockpit in front of them while keeping a good field of vision for actual visuals such as seeing the trees, ground and runwa
