How To Make A Hologram  
 

DEFINITION: Hologram -

(HOL-o-gram ) 

Usually a three-dimensional image, produced by capturing a laser light interference pattern on film. The word "hologram" is formed from two Greek words, holos (whole) and gramma (message)


Making Holograms is easy and fun with the Litiholo Hologram Kit!

For years, holograms have typically been made on a silver-halide emulsion film, like a higher resolution version of the film in traditional cameras, which required chemical baths and processing in the darkroom to see the holographic image. But just as the photography industry advanced throughout the years to making photographs with no chemical processing, holography has recently reached a similar level. In a short, five-minute exposure time, the Litiholo 2.0 "Instant Hologram" film (C-RT20) forms and develops the holographic image at the same time so it can be viewed immediately after exposure. This process involvs absolutely zero chemicals or wet ingredients, allowing you to spend all of your time making holograms, not developing them.

2. Designate your darkroom environment. Pick out a room preferably with no windows and a solid surface (such as a counter top or a sturdy table) to make your hologram. The room should be relatively free of noise or vibration, like air-conditioners, running dishwashers or washing machines.

3.Place the holographic plate holder on the stable surface with the writing face-up. The rubber matting underneath the plate holder helps minimize vibrations while holding the holographic plate in the proper place. Place the subject of your hologram within the rectangle on top of the holographic plate holder. The object should not block the laser light from going to the film, so the object will be just off to one side. Insert the holographic plate support next to the object so that the glass plate has a surface to lean on.

4. Prepare the laser diode for exposure by placing it approximately five inches (13 cm) from the object. Place the laser diode into the small laser mount on the base plate and use alligator clips to connect the battery pack and power the laser. Allow the laser diode to warm up for approximately five minutes before exposing it to holographic film.
*A heat sink clip is useful to prevent the laser diode from overheating, but be cautious not to let the clip touch ANY exposed circuitry
* If the laser diode has a focusing lens, remove the lens and the front barrel (and anything else in the way, such as a spring) so that the laser beam spreads across the entire film plate and object.

5.Utilize a blank glass plate to verify the laser beam is illuminating the object as well as your film area. Adjust the beam up or down in the small laser mount to make sure the brightest part of the spread beam is roughly halfway up the glass plate and spreads its entire width. A piece of white paper cut to the same size as the glass plate is helpful in determining the laser beam's boudnaries. When finished aligning the laser beam with the glass plate and object, remove the plate (and white paper) but leave the object in place. With the lights dimmed and paper removed, this is a good time to verify that laser light is hitting the object directly, and not bouncing off the white paper back onto the object.

6.Turn off the lights. Make sure the room is as dark as possible by shutting all doors and covering any windows, if necessary. A small LED darkroom light, a different color from the laser, is useful to navigate in the darkness.

7. Place a shutter in front of the laser beam. A folded, black piece of construction paper provides a good shutter to block all light from the laser diode when placed between the laser and the object.

8.Open the box of Litiholo 2.0 "Instant Hologram" film. Remove one glass film plate from the box and quickly shut it again to protect the other film plates from exposure. Place the glass film plate into the long slot on the holographic plate holder.

9. Wait three minutes for the vibrations to settle.

10. Gently lift the black paper shutter out of the way. Make sure that removing the shutter doesn't cause any new vibrations, so don't lean on the table or counter top and move slowly.

11. Expose your hologram to the laser light for about five minutes. Remaining silent and motionless during this step is crucial to the development of the holographic image, so get comfortable.

12. Replace the black paper shutter between the object and the laser diode, blocking the laser beam. Remove the object of the hologram and lift the black paper shutter out of theway again. To view the holographic image, look through the glass film plate where the object used to be while the laser diode is illuminating the film plate. You are now looking at your hologram made without chemical processing! *Holograms are best viewed with a specific, pointed light source, such as the laser beam or a spotlight.

Tips:

• Vibration is the enemy of holograms. When making a hologram, no talking during the exposure time; do not touch the table or surface during the exposure; don't move around or tap your feet.

• If at first you don't succeed, overexpose. The 2.0 "Instant Hologram" film develops as it's exposed so additional laser light will only have a minor effect after the film has reached exposure capacity. The exact exposure time for holograms will vary depending on the laser and objects used.


Warnings:

• Lasers provided by Litiholo have been chosen such that your natural "blink reflex" is sufficient for protection at these laser powers (5mW or less). Of course, if used improperly, any laser can cause problems. Never place a laser directly up to your eye, or point a raw laser beam into your eye while forcing your eyes open. This is roughly the equivalent of staring at the sun. Don't do it!
