Laser Refraction
Hidden Images
are a feature
unique to SANDS-SECURE®
holograms.
Using a simple
$5 laser pointer,
the field agent
irradiates a
target spot on
the hologram.
A secret image
is refracted
onto an adjacent
perpendicular
surface, verifying
its authenticity.
Just as with
nano-text security
features, this
microscopic hidden
image is too
small to be copied
effectively,
thereby defeating
counterfeiters.
This is also one of the SANDS-SECURE®
"Ease Of Detection" features that make field
training painless.
A simple
laser pointer
is used to reveal
the hidden image
in a SANDS-SECURE®
hologram.
