| The terms holograms and
holography were coined by Dennis Gabor (the father of
holography) in 1947. The word hologram is derived from the
Greek words "holos" meaning whole or complete and "gram"
meaning message. Older English dictionaries define a
hologram as a document (such as a last will and testament)
handwritten by the person whose signature is attached.
Holography is the study of three
dimensional images created using light waves that
interfere with each other. The image created is a
'hologram'. The image can be broken down into any
number of pieces (down to a lower limit) and each piece
with still retain the complete image of the entire
hologram. 
The principle of holography is used
extensively for diagnosis in Traditional Chinese Medicine
using micro systems, pulse diagnosis, tongue diagnosis and
face reading.
