P3D More Holo Info / Label Info

[Bob_Maxey@xxxxxxxxxxxx]

Actually, the holographic Images some of you are describing - those that
can be viewed in normal light, are still true holographs, not Pusedo-Holo
Images. For the most part, they are made the same way Dichromate Holo
images are made. The image is recorded and a master is made in which the
replications are made by an embossing process. Of course, there are many
additional steps in the process.

The process is changing and getting better. These days, Holo portraits are
easily made, but expensive. Also, there are some new recording materials
available - especially polymers, and laser diode light sources are being
used as a replacement for HeNe type lasers.

 What is interesting about a holograph, is that if you take one and cut it
up into fractional pieces, the entire image can be reconstructed from each
piece. The image exists at every point in the holographic image. This is
one reason why holographic computer memory research is so big; the ability
to store vast amounts of data in a small space.

And unlike stereo photography, you can actually see around objects within
the 3D image.

Concerning Stereo slide labeling approaches - I recently tried using a
machine here at work we use for printing serial numbers and bar codes on
PCMCIA Covers. It is a computer controlled printer that uses Ink-Jet
Technology, and can print as small as 2.5 Point type. Too expensive for the
home, but interesting just the same.

This experiment lead me to think perhaps if one had access to machine
tools, and old beat to heck Ink Jet printer and a little thought, perhaps
one could make a similar printer for stereo slide mounts. Just a thought.
