Transmission holograms constitute one of the two major types of holograms, the other being reflection holograms. All other holograms (rainbow holograms, computer generated holograms, multi-channel holograms, computer-generated holograms, etc.) are actually hybrids of these two types of holograms.
The typical transmission hologram is viewed with laser light, usually of the same type used to make the recording. This light is directed from behind the hologram and the image is transmitted to the observer’s side. The virtual image can be very sharp and deep. For example, through a small hologram, a full-size room with people in it can be seen as if the hologram were a window. Of course, making holograms of people requires a more powerful laser and significant safety precautions, but you get the idea. Transmission holograms are like a window to another world. Remember Alice in Lewis Carroll's Through The Looking Glass?
Unique Features of Transmission Holograms
There are some unique features of transmission holograms that"wow" the viewer:
an image of a subject much bigger than the holographic plate or film sheet that records the hologram. Reflection holograms cannot do this easily.
• Have an image can be projected onto a screen or other surface with a laser.
• Can be broken into small pieces whereby each piece still contains the entire image. Yes, that's right. If you were to smash a hologram with a hammer and then shine a laser through just one
piece, the entire image can be still be projected and viewed.
• Can record more than one image on the same holographic plate of film sheet; in effect, adding a “channel” for subsequent images. When viewing the finished hologram, you can “tune” to different channels by rotating the hologram and see your different images!
