A hologram is a visual reproduction of a two-dimensional image that appears as if it is in three-dimensional space. It works by reconstructing light waves from an object or scene into a semi-transparent, intangible illusion of light. If you want to project a hologram, it is important that you do so in a way that will be visible to your audience. Exact angles and light construction techniques must be preserved; it is currently impractical for an individual to create a hologram that is visible from all angles and in all light conditions.
Set up your holographic film plate—a plate of glass with a holographic image burned onto it—so that your light source can illuminate it and shine through it directly. Make sure that the light source is pointed at your projector screen and that it is at least 3 feet away.
Turn off all lights.
Turn on your light source.
Walk back and forth in a 180-degree axis around your hologram. You should be able to see your hologram appear to rotate or change spacial relationships between other objects within the image.

Make sure that your light source is pointed at the the holographic film plate at the same angle as the light source was when the the film plate was created. For example, if the film plate was made at a 30-degree angle, the light source will also have to hit the film plate at about the same 30-degree angle. If you purchased the film plate, the retailer should be able to tell you what angle to view it at.
