Accurate Holograms Savings Lives, Money, and Time (Forbes Magazine)
NEW ARTICLE
The U.S. military is testing a new breed of holograms to strategize during
the current conflict in Iraq. The technology, developed by Zebra
Imaging, allows holograms, large and small, to be viewed from any angle
without distortion.
Fast Holography of Faces (Optics.org,
Institute of Physics)
NEW ARTICLE
Facial surgery and forensic science are
benefiting from a portable holography system called digital holographic
facial topometry that can capture the shape and texture of faces in an
instant.
Holographic Data Storage: Light on the Horizon (The Economist)
It will soon be possible to
use holographic techniques to store a terabyte (1,000 gigabytes) of data on
a CD-sized disk. Today's DVDs,
by comparison, have a storage capacity of less than 20 gigabytes. As early as 2006,
InPhase
Technologies of Longmont, Colo., will be introducing a
storage drive that records data on holograms. The company may be the first
to launch this new kind of holographic-based storage device. A number of companies on the verge of
marketing Holographic Versatile Discs (HVD) technology,
including Sony and Fuji (CNET).
Holograms
to Help Fight Diabetes (Tornado Insider)
Smart Holograms, a British
start-up, is exploiting hologram technologies to detect the presence of
specific human disease analytes. Their first product based on this
technology is a novel glucose sensor for diabetes self-testing. You
can learn more about holographic biosensors in the
OE Magazine (by SPIE) article on this subject or a brief article by
Jeff
Blythe, a contributor to the development of this technology.

Move Over DVDs: NTT Develops Stamp-Sized 1GB Mobile Media (Asashi)
Nippon Telegraph & Telephone (NTT) announced that they will commercialize
1GB mobile media cards the size of a postage stamp.
Based on thin-film
holography, NTT sees
this as the next-generation DVD format and more.
Making Holograms in the Classroom (SPIE--Int'l Society for Optical
Engineering)
Simple holograms demonstrate
the principles of light and wave theory, as well as teach photonics
problem-solving skills to students. Students learn light and wave theory
(reflection, refraction, diffraction, interference, and polarization) and
have fun doing it.
The Holographic Principle (Scientific American)
Is the world as we know it
really a hologram? In some sense, yes. The cover story of the August 2003
issue of Scientific American, "Information
in the Holographic Universe", writes that theoretical results about
black holes suggest that our universe may be like one gigantic hologram.
Hands of Light (Scientific American)
New technology that uses
"holographic optical tweezers" to trap and move objects the size of a
protein (five nanometers) or a collection of cells (100 microns) may have
large implications in medicine and other fields. See also the extensive research notes of
Professor David Grier
at New York University on this subject.
'Touchless' kiosks a reality (New York Times news service)
Connecticut-based HoloTouch,
Inc. recently joined forces with InfoPerks LLC. to create "touchless"
holographic keyboards for information kiosks that would be placed on
sidewalks of New York City. The kiosks use holographic
keyboards that float in the air.
